Mating Rose Chafers

Dear D DRAKE,
These are mating Rose Chafers,
Macrodactylus subspinosus, and you may verify our identification on BugGuide which states:  “Adults emerge in early summer and feed on flowers, some leaves. They live for up to 6 weeks. Mating occurs on food sources. Eggs are laid deep (13-15 cm!) in soil and hatch in one to three weeks. Larvae feed on roots and overwinter deep in soil. Pupation in early spring in the soil, just under the surface.  Adults contain cantharadin, can poison chickens, other birds.”  We do not provide extermination advice, but now that you know what you are dealing with, you can do additional research.
