My favorite roach species, the ivory-head roach has made a veritable name for itself as an excellent feeder and cockroach of choice for blatticomposting (composting using cockroaches). The nymphs are extremely bulky, and a close look at their forelegs reveal a very bulky tibia and a very tiny foot; this is a modification for digging, shaped much like a shovel (unlike the slender running legs of other roaches with long tarsi, or feet). It is a docile, large species that tolerates crowding very well, with a steady reproductive rate.
The history of the identity of this strain is complex. Depictions of “Eublaberus distanti” in the early 2000s show what has long been cultured as six-spot roaches. This includes photos from academic sources that would have been reviewed by roach experts such as Dr. Louis Roth. However, the type specimen for distanti is clearly an ivory-head roach, and images in Cockroaches: Ecology, Behavior, and Natural History show wild ivory-heads labeled as Eublaberus distanti. It is likely that six-spot roaches are either an undescribed species of Eublaberus, another species that has been misidentified for quite some time, or “true” biolleyi described after ivory-heads and then incorrectly synonymized.
