Soldier Beetle

Cantharis rustica


One of the common soldier beetles, caught just during the dinner-time - I wish I knew what kind of caterpillar this would be... This soldier beetle has black elytra covered in fine hairs, with the tip of abdomen protruding below elytra. The pronotum is brown red with a dark mark in the center - the position of this mark differentiating it from another common soldier beetle of same colours, C. fusca. Moreover, femurs are red-brown too; while legs are all black at C. fusca.


Native to Europe, it is usually found on uncleared edges of roads or agricultural fields. Here, observed on edges of wetland in an area of mixed use (agricultural fields and some protected wetlands and woods), all located in Geneva lake valley, French side.


I thought i could be C.rustica; but all descriptions I managed to found state that femora (thighs) are red with species; which is not the case here, as they are black or dark brown...

Great series Zlatan! That caterpillar looks like it was made out of a deflated snowpea with a moldy lychee head :D Thank you for sharing :) Liana
