Grizzled woolouse fly - Stevenia deceptoria

Order Diptera
Family Rhinophoridae
This species is a parasitoid of isopods like sowbugs. The female does not lay the egg inside or outside the host but in the area the host frequents. When the larva hatches, it stands up and when the host passes by the larva attaches to it and gets into the host. It feeds on the insides to leave an empty skeleton when the adult fly emerges.
