size difference
Is the noticible difference in size just male and female?

male and female?
I don't know. In the collection I did notice a fairly wide array of size differences (a few nearly twice the size of the smallest ones), but made no attempt to check the sexes of the beetles.

OK
I knew they looked alike, but the big size difference threw me.
