Whirligig Beetle (Family Gyrinidae) Likely Gyrinus spp.

CENTRAL FLORIDA CRITTER OF THE DAY: Whirligig Beetle (Family Gyrinidae)

Note his friend the fishing spider (to the left) sharing the plant.

This insect travels at dizzying speeds across the water. I’ve watched them for years but this is the first I ever saw one rest on vegetation.

Because of the small size I believe this is in the Gyrinus Genus.

It may just be a small Dineutus spp. although I think I see the scutellum in the picture below. They say it is concealed in Dieutus. A defense mechanism for these beetles is to give off an apple odor giving them another common name of apple bug.
