Austral Ellipsidion Cockroach

Posted by Darren on May 9, 2010

I’ve been hoping to find an example of the Austral Ellipsidion Cockroach (Ellipsidion australe) as my first entry for the Order Blattodea.  As the cockroach is generally not perceived as a beautiful insect, I’m glad to find an example of a beautiful species of bush cockroach here in Australia.  I don’t know a lot about this species of cockroach, but it does seem active in the day as opposed to other (more despised) species.   I find the appearance of both mature and immature specimens of this cockroach quite impressive.  I also think the patterns on the back resemble that of a decaying leaf.  These bush cockroaches are not known to inhabit the home like the introduced species, and are usually seen living off the ground in plant foliage.  The adult female in these photos can be seem carrying an ootheca (egg sack) attached to her abdomen.

The last photo is an example of a small nymph of Ellipsidion australe.  I only managed one shot of this cockroach before my intrusion caused the nymph to dart off in the foliage.
