Head of a Prionid Beetle

Dear Kerri,
We feel like we have been involved in a Sherlock Holmes novel or a CSI episode.  This is the head of a Prionid Beetle, and there are numerous species that might be encountered in New Hampshire.  Our most likely subject is a male Broad Necked Root Borer,
Prionus laticollis, which is pictured in our archives and on BugGuide where it is indicated that:  “Antennae have 12-13 segments.”  The head you found appears to have 12 segments on the antennae.  The big question is how did that head get on your deck.  Birds will sometimes eat fatty insects, and the body of a Prionid Borer is full of fat, and the head hasn’t much nutritional value, not to mention it is harder and less palatable.   BugGuide also indicates:  “Males are attracted to lights.”  This is a male as females have much less developed antennae.  If this Prionid was attracted to a light and your house cat encountered it, perhaps the cat ate the body of the insect and left you the head as a trophy.  The predator will have to remain a mystery.

    That’s definitely quite strange, and fun to try to figure out, but I do feel sad for the poor little thing. If it was windy and the windows were open, it could have been blown in from somewhere. Sometimes birds will just eat the bodies of insects, and regurgitate the rest of it up because it gets caught in their throat.
