Nathalis iole – Dainty Sulphur

Caterpillar food: plants in the Compositae – aster family

This tiny butterfly doesn’t overwinter in Wisconsin – it flies up from farther south.  It’s wingspan  – with wings spread – is about one inch.  It’s not common here – I’ve only seen it a few times.  I saw several during the summer of 2007, and even more in the summer of 2012.

This was the first one I ever saw – in Pepin County, on the roadside in front of the farm stand where we’d stopped to buy produce.


That fall I saw quite a few Dainty Sulphurs on our driveway – never more than a few at a time, but they were there nearly every sunny day until the weather got cold.

The next time I found Dainty Sulphurs was in late August 2012.  There were at least 5 or 6 fluttering around our driveway, near the house.
