Hover Fly Pupa and Oleander Aphid (at far right)

Dear Joanne,
This is the pupa of a beneficial Hover Fly or Flower Fly in the family Syrphidae, and while in the larval stage, they feed voraciously on Aphids.  Adult Hover Flies are also excellent pollinators that mimic stinging wasps and bees, though they are perfectly harmless to humans.  We located a matching image on BugGuide, and there is also a small image at the bottom of the Bugs and Critters in my Florida Back Yard blog.

Thank you!  Do you know if Hover Flies are harmful to Monarch caterpillars?
Joanne

Hi aganin Joanne.  They are not harmful to Monarch caterpillars.
