Gyrinidae

Here’s something strange: the compound eyes of a whirligig beetle are divided into a higher part that is above water level when the beetle is floating passively, and a lower part that sits below water level. Gyrinidae are the only type of beetle with this feature.

The antennae are also unusual among beetles, being short and plump, and placed about at water level. 

Whirligigs get their common name from their habit of swimming rapidly in circles when alarmed. Adults carry an air bubble under the elytra at the tip of their abdomen, allowing them to breathe underwater. They are very social creatures, often found in large numbers swimming around on the water’s surface. There are about 700 species worldwide.

After work

Before driving home from my shift at the state park visitor center, I sat under a tree in the parking lot to record thoughts and sounds. I really love my (volunteer) job. The people who come in — they want what we’re selling. I don’t mean drinks and branded swag, but hiking trails, wildlife, history, geology, a respite from the city. It’s such a pleasure to answer their questions (and provoke more), show them something they‘ve never seen, give them a new experience, or provide a comfort.

And when your colleague sends you home with a bunch of art supplies? Bonus! (thanks Dave!)
