Pie Dish Beetle

Hi Marian,
We doubt that we will be able to fully answer your question before rushing off to work, but we will give you what we have found.  This beetle is very similar to one we identified many years ago, so we searched the Australian beetles in our archive and found a posting entitled Pie Dish Beetle from 2006.  We followed our own links to the Brisbane Insect Website and thought there are obvious similarities, there are also differences, notably the lack of spikes on the Brisbane examples.  We are confident that we are on the right track, but the species and genus are uncertain.  Additionally, the image from our archive is also different.  Perhaps someone can provide a more exact response and we will continue to research as time permits.

We did find a Hairy Backed Pie Dish Beetle, Helea perforata, on FlickR, and that resembles our previous posting, but the spikes on your beetle are thicker.

  1. We have found about 6- 12 flat round bugs, dark in color, usually climbing slowly up a wall. They are about 1 inch around. We have never seen them before. We live in Long Beach California 90808.
