Working in California Valley and have seen a few of these insects slowly crawling around. There are flies everywhere, tons of them, but just today caught a slow mover munching on one of the flies, hence becoming a welcome addition to my home. They’ve been doing well too as they’ve left a pile of leftover carcasses at the base of their attack.
Just wondering what it is.
Thanks,

Dear Chris,
The predator is an Assassin Bug in the genus
Zelus, and the prey appears to be a Flesh Fly.  We believe the Assassin is a Leafhopper Assassin Bug, Zelus renardii, based on this BugGuide image.  According to BugGuide:  “Generalist predator (despite its common name suggesting host specificity).”  Zelus Assassin Bugs seem to bite humans more readily than most other Assassin Bugs, with the exception of blood-sucking Kissing Bugs, and though their bite is not considered dangerous to humans, it may leave the bite site tender and swollen.  They should be handled with caution to avoid bites.
