Whirligig Beetle (Ventral Surface) with Air Bubble - Dinetus emarginatus TL: ~10 mm. Broadly oval, bronzy black with a shiny ventral surface. Males have padded front tarsi. They have divided eyes and paddle-like legs.<br /> <br /> Whirligigs are awesome, here are some reasons why:<br /> -They are the only aquatic beetles that use surface tension for support. They move about on the surface of the water erratically<br /> <br /> -They will expel defensive secretions (which smell like apples) from the tips of their abdomens if disturbed. This secretion is also a water repellent, which lowers surface tension so the whirligigs can ride a wave of recoiling water molecules!<br /> <br /> -They carry an air bubble around with them on the tip of the abdomen, which they breathe in when they are underwater.<br /> <br /> Habitat: Collected from a woodland pond and photographed at home.<br /> <figure class="photo"><a href="https://www.jungledragon.com/image/94344/whirligig_beetle_dorsal_surface_getting_an_air_bubble-_dinetus_emarginatus.html" title="Whirligig Beetle (Dorsal Surface) Getting an Air Bubble- Dinetus emarginatus"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/3232/94344_thumb.jpg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1759968010&Signature=Sn7UdyggNZUiRrjQ6JsjM9LqdpQ%3D" width="200" height="156" alt="Whirligig Beetle (Dorsal Surface) Getting an Air Bubble- Dinetus emarginatus TL: ~10 mm.

Whirligig Beetle (Ventral Surface) with Air Bubble - Dinetus emarginatus

TL: ~10 mm. Broadly oval, bronzy black with a shiny ventral surface. Males have padded front tarsi. They have divided eyes and paddle-like legs.

Whirligigs are awesome, here are some reasons why:
-They are the only aquatic beetles that use surface tension for support. They move about on the surface of the water erratically

-They will expel defensive secretions (which smell like apples) from the tips of their abdomens if disturbed. This secretion is also a water repellent, which lowers surface tension so the whirligigs can ride a wave of recoiling water molecules!

-They carry an air bubble around with them on the tip of the abdomen, which they breathe in when they are underwater.

Habitat: Collected from a woodland pond and photographed at home.
