This week brings us a photograph with lots of action. The pale round objects are the eggs of stink bugs, and from one has emerged a male parasitic wasp (Trissolcus euschisti). As is typical for this genus, the males emerge first and fight for access to the females to mate with them as soon as they emerge. The males can often be seen "drumming" on the eggs as the females begins to emerge. Here the male eagerly awaits the emergence of a female who has just begun to chew her way out.
