Gymnosoma rotundatum (Linnaeus, 1758) Common name “Ladybird Fly” (A shield bug parasitoid fly).
Flight season…June to October
Size: Length: 4.5mm to 8mm “Gymnosoma” translates into “naked body” quite possibly named, as they are noticeably less bristly, than other Tachinidae flies.
Hosts: Ladybird flies are parasitic and lay their eggs on Sheild bugs, after hatching the larvae bore into the unfortunate Sheild bug. When the larvae are near the stage of pupating, they exit the Sheild bug and pupate in the ground.
