male Meloe... [americanus??]
dates may be critical with these :/

 
gender ID
Males of this genus have a crook in their antennae. The species have explosive emergences where all of the adults are alive for a few days, mate and die, which is why the date is important. Their presence is ephemeral. They can blunder around because they are heavily chemically defended giving them the common name "blister beetle".

 
Many thanks all.
Many thanks all. I've already found the elaborate mimicry the larvae use to disperse and find food:

Insect DNA is incredible!
Also found a reference that says some Meloe live longer than a few days:
