Soldier Beetles

A pair of Rhagonycha fulva (Coleoptera: Cantharidae) mating. 

In this species the males have distinctly larger eyes than the females, presumably this has evolved because the males search out the females by sight.  It is common amongst the flies for males to have larger eyes than females but this is the first time I have noticed this in beetles.
