Green Bottle Fly

Dear Marlene,
This looks to us like a Green Bottle Fly,
Lucilia sericata, which is pictured on the Natural History of Orange County and on BugGuide.   According to BugGuide:  “Larvae feed on carrion. Adults take nectar and have been used as pollinators of onions, cabbages and also other Brassicaceae” and “Larvae are used in forensics to determine the age of a corpse, and in medicine to clean up wounds (they feed on partially decomposed tissue, leaving the healthy one alone).”

Location: San Diego, California
