      Pseudophoraspis nebulosa (Burmeister, 1838) - probably!

      Pseudophorapsis nebulosa (Burmeister, 1838) is a very variable species, both in size and coloration. It is quite commonly found in the rainforests of Borneo. I have found it in Brunei, Kalimantan, Sarawak and Sabah. I have found it to be relatively rare in Sabah, however most of my collecting in Sabah has been at higher altitude than my collecting elsewhere and it is possible that it is restricted to lowland areas. This photograph was taken in lowland Sabah. Unfortunately the specimen escaped so I have not been able to confirm the identification. Photo copyright Phil Bragg.

      Cockroaches: An Amazing Diversity

      By George Beccaloni (Curator of cockroaches etc, The Natural History Museum, London)






      Eucorydia aenea dasytoides fom China. Copyright Guo-Fang Jiang.Elliptorhina javanica. Male. Copyright George Beccaloni.Blattellid cockroach from Madagascar. Copyright George Beccaloni.
      Cockroaches (order Blattodea) are a group of largely omnivorous insects with incomplete metamorphosis which together with the carnivorous praying mantids (order Mantodea) form the superorder Dictyoptera. It is thought that cockroaches split from the common ancestor they shared with the mantids during the Lower Cretaceous about 140 million years ago. The cockroach-like species ("roachoids") with external ovipositors (egg laying tubes) which existed before this split, originated as far back as the Upper Carboniferous period some 315 million years ago. Recent studies (e.g., Inward, Beccaloni & Eggleton, 2007; Eggleton, Beccaloni & Inward, 2007) have shown that the termites are actually a lineage of cockroaches (epifamily Termitoidae) and not a separate order of insects as previously thought. Termites are most closely related to the wood-feeding cockroaches of the genus Cryptocercus, with which they share many structural characters and behavioural traits. Although termites are cockroaches we are only concerned here with the six families of 'true' cockroaches: Nocticolidae, Polyphagidae, Blattidae, Cryptocercidae, Blattellidae and Blaberidae.

      Cockroach diversity


      To date approximately 4,500 cockroach species have been named and there are probably at least twice this number still to be discovered worldwide. Although most species are found in the tropics a few occur in temperate regions. There are about 130 native European cockroaches and, perhaps surprisingly, new species are still being discovered in this well studied region.


      Regrettably most people seem to regard all cockroaches as offensive and destructive vermin. However, this reputation is deserved by less than 30 species (< 1% of the total) - the vast majority being secretive insects which never associate with man. As a group cockroaches exhibit a remarkable diversity of size, form, coloration and behaviour and occupy a very wide range of habitats from caves to mountains, from rainforests to deserts.

      Some tropical cockroaches are thought to live only in the nests of social insects and there are even amphibious species which dive under water when threatened. Although most cockroaches are probably omnivorous, the ability to feed exclusively on rotting wood has evolved at least three separate times: in the ancestor of Cryptocercus and the termites; in the blaberid subfamily Panesthiinae; and in the blaberid Parasphaeria boleiriana.

      Many cockroach species are wingless or have reduced wings and some (e.g. the Cuban burrowing cockroach Byrsotria fumigata) have fully winged males and females with greatly reduced wings. Asian and Australasian Panesthia species, which burrow in decaying wood, have well developed wings when they first become adults, but these soon break off about one third of the way down their length, presumably once the insects have dispersed. Many cockroaches are sexually dimorphic, for example the Madagascan hissing cockroaches (Gromphadorhina and their relatives) which are often kept as pets. The males of these cockroaches have well developed 'horns' on their pronota (the plate covering the head) which they use to fight rival males - the largest individual usually emerging as the victor.








      Lucihormetica fenestrata. Male. Copyright George_Beccaloni

      Adult male Lucihormetica fenestrata from Brazil.


      The males of one South American cockroach, Lucihormetica fenestrata, have raised yellowish tubercles on their pronota which are bioluminescent and may play a role in courtship. It is currently unknown how this bioluminescence is produced, but one suggestion is that the spongy material inside the tubercles harbours bioluminescent fungi or bacteria which the cockroach may acquire from the rotting wood in which it lives. Related species have similar tubercles which may also emit light.


      The world's heaviest cockroach is the wingless Australian rhinoceros cockroach (Macropanesthia rhinoceros), which weighs up to 33.5 grams and has a body length of up to 80 mm. It has one of the most complex life-histories of all cockroaches and, with a lifespan of more than 10 years, it is among the longest lived of all insects. The species with the greatest wingspan is the Central and South American Megaloblatta blaberoides, which has a spread of up to 185 mm. The smallest is the North American Attaphila fungicola, which measures less than 3 mm long and lives in the nests of leafcutter ants.

      Reproductive biology


      Cockroaches are more diverse in their reproductive biology than probably any other order of insects. One species, Pycnoscelus surinamensis, is parthenogenic (the ability to reproduce without mating), but males are found in all other species which have been studied.

      Ootheca of Archiblatta hoeveni from Malaysia.


      Species in the families Nocticolidae, Polyphagidae, Blattidae, Cryptocercidae and most Blattellidae, produce hardened oothecae (egg cases) which are dropped on the ground, buried, or attached to substrate using a salivary cement. In contrast, species in the family Blaberidae plus a few Blattellidae, have membranous oothecae which are incubated in a brood sac within the female's body until the eggs hatch. One blaberid, Diploptera punctata, has a greatly reduced oothecal membrane which does not cover the eggs. Remarkably this species produces a nutritious 'milk' from the wall of the brood sac on which the developing embryos feed. Species in the blaberid subfamily Geoscapheinae have lost the oothecal membrane altogether and the eggs are deposited straight into the brood sac. These cockroaches exhibit a high level of parental care. The nymphs live with the mother in her burrow until they are about half grown and the female provides food for them by pulling dead leaves and other vegetation into the burrow.

      The most unusual parental care is exhibited by species in the blaberid subfamilies Epilamprinae and Perisphaerinae. Thorax porcellana, a species of the former subfamily from India, carries its young (i.e. nymphs) under its domed forewings for their first two instars. The nymphs obtain liquid food from specialized pores on the upper surface of their mother's abdomen and they also pierce her cuticle with their specialized sharp mandibles and feed on her blood (haemolymph)! Species of the genus Perisphaerus (Perisphaerinae) from South-East Asia and Australasia have a somewhat similar mother-offspring relationship. When the nymphs are born they are white, blind and have strange tube-like mouthparts, which are unique amongst cockroaches. The mother has four apertures at the bases of her mid- and hind legs into which the mouthparts of the nymphs exactly fit and the nymphs are believed to suck up a nutrient 'milk' from these pores. The nymphs cling beneath the mother's body for the first two instars and only in the third instar do they develop normal eyes and body pigmentation.

      Predator defences

      Female Perisphaerus sp. from Malaysia rolled up into a defensive ball.


      Cockroaches have evolved a wide range of strategies to avoid being eaten by predators. Most, like the leaf green Panchlora species, rely on camouflage, whilst a few have warning coloration or mimic distasteful insects (e.g. Prosoplecta from South-East Asia, which mimic ladybird beetles, Coccinellidae). Cockroaches of the genus Perisphaerus roll up into a ball like pill millipedes or woodlice when molested, but most depend on speed and agility to escape. One currently unnamed South African species of Blattellidae has greatly enlarged hind legs which enable it to jump like a grasshopper. This species hops between grass stalks and apparently specialises in eating bird droppings.


      A few cockroach species possess active defence mechanisms. These include spraying repellent fluid from abdominal glands like Diploptera punctata or Archiblatta hoeveni and producing startling noises by expelling air rapidly through abdominal spiracles, as in the Madagascan hissing cockroaches (Gromphadorhina and their relatives).

      Studying cockroaches


      Apart from extensive studies of the major pest species very little work has been done on cockroaches as a whole and they remain relatively neglected by both amateur and professional entomologists alike. The majority of species are easy to keep and breed in captivity and they don't require a constant supply of fresh leaves like stick-insects or live-foods like praying mantids. Why don't you start keeping and studying them? There is still a lot to discover!

      Die ?Blattodea Culture Group? (BCG) ist eine nicht gewinnorientierte Gesellschaft ohne wirtschaftliche Interessen. Sie wurde 1986 mit dem Ziel gegründet, die weltweite Erforschung von Schaben zu fördern. Die BCG gibt die Farbzeitschrift ?Cockroach Studies? heraus, die ein bis zwei Mal jährlich erscheint und deren Beiträge von Schabenzuchten über Sammelreiseberichte bis hin zur Beschreibung neuer Schabenarten reicht.

      Die BCG richtet zweimal jährlich Treffen aus (in England und Deutschland), auf denen Mitgliedern Vorträge geboten werden und ein Austausch von Lebendmaterial stattfindet. Die Gruppe pflegt eine Liste aller ihnen bekannter in Zucht gehaltener Arten, die zu einem groÿen Teil auch von dem BCG ?Livestock? Koordinator gepflegt werden. Die Zuchtüberschüsse des Koordinators und der Mitgliedern der Gesellschaft werden auf den Treffen verteilt.

      Besucher dieser Seite, die Informationen über Schaben suchen (eher als über die BCG), sollten den Artikel  ?Cockroaches: An Amazing Diversity? lesen. Zahlreiche Informationen finden sich ebenfall in den alten BCG Newslettern. Demnächst wird die ?Database of Cockroach Literature? hunderte nicht mehr copyright geschützte Artikel und Bücher über Schaben enthalten.

      World Cockroach Catalogue

      BSF logoA comprehensive world catalogue of cockroaches called the Blattodea Species File (BSF) is now available on the Web see:-
      http://blattodea.speciesfile.org/HomePage.aspx
      . The catalogue contains approximately 6,420 scientific names and of these about 4,560 represent valid cockroach species. For more information about the BSF and what information it contains please see http://blattodea.speciesfile.org/Database.aspx.

      If you notice any errors or names which are missing from the BSF then please inform the author, George Beccaloni (blaberus1@ntlworld.com). In addition, if you are a taxonomist and describe any cockroach taxa in the future then please send George a copy of your publication (as a pdf file if possible) so that he can keep the BSF up-to-date.

      Your help is needed!

      One of the main long-term goals of the BSF project is to make available photographs of all cockroach primary types, plus images of living individuals, photographs of genitalia etc. Having a comprehensive set of photographs of world cockroach species available on the Web would be of great benefit to everyone who is interested in cockroaches. Please note that if you have any images which you would like to include in the BSF, then please send them to George by e-mail or on CD/DVD. JPEGs are preferred and image files should ideally be no larger than 1MB. If you do not hold the copyright of an image then please ensure that you have the permission of the copyright holder to publish the image on the Web. If you own the copyright then that will be stated in the BSF. You could also add copyright information as text to the bottom of the image as in the picture below.

      Sponsors Needed!

      Can you help?

      Cockroach Studies is a high quality journal which is costly to produce because it is printed in full colour. Unfortunately the cost of producing two issues per year is currently greater than the money the BCG receives in membership fees, so until membership numbers increase the Group will either have to produce only one (larger) issue of CS per year, or find sponsorship to subsidise the production of the second issue. The second option would be the ideal one, so if you or your company are interested in possible sponsorship then please contact George Beccaloni. Even pest control companies are welcome! Sponsors will be given either a full page or half page in CS to advertise their company, depending on the level of sponsorship.

      A History of the BCG

      By Adrian Durkin (Exhibitions Officer, Dudley Museum and Art Gallery, Dudley, UK)

      Many years ago, on a dark and wet Saturday in October, I attended the Amateur Entomological Society (A.E.S.) fair at Hounslow Civic Centre, London, England. In many ways this was an ideal location for such an event because the building is clad in what appears to be Purbeck Roach Stone. Regrettably this does not refer to the fossil content but none the less it is of interest as it is mostly composed of the internal moulds of gastropods.

      Quite close to the entrance I encountered a young entomologist selling quite a number of different invertebrates but with a marked bias towards cockroaches. At that stage I had been collecting them myself for about a year or two and had possibly eight or so species. It is so long ago now that I cannot recall what first attracted me to these insects. I think however it was the number of different forms and the subtle variation within the group. I had graduated to cockroaches from their fellow orthopteroids, stick insects. It is hard to imagine a greater contrast between groups which in evolutionary terms are quite closely related.

      As the day went on and the stalls became less busy it was possible to engage the proprietor of the stall in conversation. Surprisingly he had not sold all of his roaches, indeed far from it, there seemed little demand. His name was Darren Mann and as our conversation progressed it became clear that he too was a cockroach enthusiast and had a similar number of species to myself, although different ones. Instantly, allowing for some duplication, the combined culture list had grown to about 12 species.

      It was instantly apparent that the same idea was forming in each of our minds, that of forming an appreciation society. However the revelations of the day did not end there because Darren introduced me to his friend George Beccaloni, who, like Darren, was just a young innocent! And fresh-faced student in those days. It transpired that George too kept cockroaches and had a few that neither of us had. The collective culture list jumped for the second time that day to about 15 and the likelihood of there being an appreciation group evolved further.

      As time went on it was decided to develop the idea and we publicised ourselves through appearances at fairs such as one in Leicester and of course the A.E.S. The first hurdle was to find a name for the group. I personally felt that it was a bit pretentious to call ourselves a study group as there was no guarantee that we would do any studying. I was also anxious to keep the group down-to-earth by calling it the Cockroach Culture Group. I was able to convince the others about the culture element but they felt that a scientific name was preferable and so we became the Blattodea Culture Group. I now realise that this was the right decision not because it was scientific but because it obscured the truth. No one feels threatened by blattids whereas they start getting paranoid if you keep cockroaches!

      In the early days the group went well and membership peaked at around 120, whilst I think that the species list went up to about 40. We began the newsletter too (that was in 1986). The first edition was just two pages and did not have much about cockroaches, even the second edition was not a major study document although it did carry an article pondering how many different Blaberus species there were in captivity. However after five or six years problems began to develop. It seemed to be the usual one, amateur members did not consider themselves competent enough to write articles whilst many of the professional entomologists in the group could not get the time to write articles. None the less the group continued producing newsletters up until Volume 14 in 2000. Both Darren and George became professional entomologists although George corrupted himself by doing his PhD on butterflies (traitor). Fate however has moved events full circle. Darren is now a curator at one of the two most important collections of cockroaches in England, that of the Hope Collection at the Natural History Museum in Oxford. George on the other hand has recently become curator of the other, the Orthopteroidea collection of The Natural History Museum in London. Neither of these things in themselves would have resurrected the fortunes of the group but we have been fortunate to get the interest of Ingo Fritzsche who has managed to mobilise much support for the group in Germany. He has been able to bring on board the valued services of Roland Dusi from the German chemical firm frunol delicia. It was with kind support from them that we were able to have a re-inaugural meeting at Delitzsch near Leipzig in Germany. The company keeps over 100 different species of cockroaches in their research collection and they were kind enough not only to host the meeting but to give us access to the collection. In the face of inspiration like this it would be impossible for the group not to feel a new sense of purpose and we therefore hope to resurrect the society. Who says phoenixes have to be birds?

      About the Blattodea Culture Group

      The Blattodea culture Group (BCG) is a worldwide group of cockroach enthusiasts and amateur and professional entomologists. As well as content generated by the Group this site uses a taxonomy provided by the Blattodea SpeciesFile to display information from numerous resources on one page (use the Taxonomy Search or browse the cockroach taxonomy.

      The Group publishes a full colour journal, Cockroach Studies, which is distributed to members. Members of the group also have access to free livestock (for a list of species that have been in culture see the BCG Culture List) and are able to attend the Group's meetings.

      The BCG also runs The Cockroach Forum, an online discussion board for all things to do with cockroaches.
