TreeHugger Soldier

This little guy got into my pants yesterday! 😁 What is it? This is a Treehugger Soldier Beetle (Dichelotarsus piniphilus) in the family Cantharidae or soldier beetles ( because their wings resemble military uniforms). More interesting though is the Greek translation of Cantharis or κανθαρισ, translating to ‘blister beetle.’

I’m pointing this out because this little Treehugger got confused yesterday and when it was hugging my leg and my pants were hugging back a bit too tightly, it either bit me or exuded some of the defensive chemicals that they use to repel would-be predators . In either case, I was fine aside from a bit of a temporary stinging sensation.

This species is common in the west. Surprisingly, very little is known about the life histories of these beetles. I’ve spotted them on nettle this time of year. Adults are known to feed on insects (including aphids), nectar, and pollen.


I wondered if there is some uptake of the chemical constituents of the nettle to produce the defense secretions in the beetle, either via consuming pollen from the nettle, or via feeding on another insect feeding on the nettle. A literature search failed to yield any supporting information, though I did find an older publication listing insects found in association with nettle. Quite a few were some of our lovely Lepidoptera, so you might want to leave those nettle patches instead of clearing them away πŸ¦‹
