Last night was a nice night – calm and not so hot, but still warm enough for the moths to come out. Lots of people came to visit the lights. I hope you’ll all come back again! It’s fun to share the experience. It does take some patience – the interesting creatures are slow to come out. Most of the best ones show up around 10:30 or 11.
Here are the new moths – and other creatures – I saw.
The first one to show up – a Katydid – I don’t know anything about Katydids, so I don’t know which one.
I always see lot of Caddisflies – this is a large one – about 1 1/2 inches long. Caddisfly larvae are aquatic. The larvae of many species build casings for themselves out of sand or algae. They drag it around with them, and hide inside when they feel threatened.
Another smaller species of caddisfly
The Gem – I’d love to know about moth names that start with “The”. There are many of them – I suspect they’re old names for moths that were fairly common and easily recognized – but I don’t know. This is a male. The female has a white spot on each forewing.
Minor Angle Moth
I realized that the moths rest on the surrounding vegetation too – not just on the sheet. This one was on one of the tree trunks. It’s a Serpentine Webworm Moth.
Elegant Grass-veneer Moth
This is an interesting one – I’d never seen it before. It’s very small – less than 1/2 inch long. It’s called a Two-banded Petrophila. It’s the first specimen on Bugguide for Minnesota. It’s caterpillars are aquatic. They live in silk webs in fast running streams. I can’t imagine where they found a fast running stream near 1666.
I also found several odd little creatures.
This is a Woodlouse. Woodlice are crustaceans – not insects. They eat decaying plant matter.
This is a European Earwig. Earwigs are insects, and they don’t actually get in anyone’s ears. They are scavengers, eating plant matter and small insects.
These next two are Leafhoppers – small insects that feed on leaves or sap of plants. They don’t have common names.
And a few beetles. This one is a False Bombardier Beetle.
