Adult females can be from {{convert|30|to|40|mm}} long. Males are slightly smaller (body length {{convert|29|mm}}) and have dark brown wings, which are absent in females. It is stoutly built, with a reddish head and brown to black body segments with prominent yellow margins.[1] The femora are heavily spined, with the hind tibiae having two very broad ridges with only two rows of spurs.[1] They are nocturnal and herbivorous.[2] Unusually for insects, it gives birth to 18–24 live offspring and protects the young for a while after giving birth. Family groups are found in late summer and autumn: a brood of black nymphs, a wingless female and two or more males, all living in a hidden crack.[2] When alarmed, it raises its abdomen into the air and squeaks loudly;[1][3] it also releases a foul-smelling liquid from glands on the back [2] when handled and alarmed, producing an indelible brown stain on skin. The only other species in the genus Aptera, A. munda, is rare, and is found in the Richtersveld.[1][3] References1. ^1 2 3 4 {{cite book |author=PICKER, M. |author2=GRIFFITHS, C. |author3=WEAVING, A. |last-author-amp=yes |title=Field guide to insects of South Africa |series= |publisher=Struik Publishers |location=Cape Town |year=2002 |pages=440 |isbn=1-86872-713-0}} {{Taxonbar|from=Q4668037}}{{cockroach-stub}}2. ^1 2 {{cite book |author=PRENTER, C. |title=Geïllustreerde gids tot die dierelewe van Suider-Afrika |series= |publisher=Sunbird Publishers |location=Kaapstad |year=2010 |pages=368 |isbn=978-1-920289-28-7}} 3. ^1 {{cite book |author=WEAVING, A. |author2=GRIFFITHS, C.L. |author3=PICKER, M. |last-author-amp=yes |title=Field guide to insects of southern Africa|series=Field Guide Series |publisher=Struik Publishers |location=Cape Town |year=2005 |pages= |isbn=1-77007-061-3}} 3 : Cockroaches|Insects of South Africa|Insects described in 1784 |
