These have been flying around my plants recently, and I just started finding them all nice and digested in reopened fly traps. Anyone know what they are? They're shiny bluish-black.
Looks like Chalybion californicum.
they eat spiders and caterpillars, depending on the species. I recently found a fallen nest full of larvae and paralyzed--but still alive--spiders for the larvaes food. nomnomnom. Very cool bugs.
