Basking Butterflies

The strong Arctic blast came through southern Illinois before midnight last night. The sun does shine. A northwest wind, gusting to 25, has the windchill at -22.  I didn’t post this blog the end of October when I wrote it. For obvious reasons, today seemed the right day for posting it.

A hard frost changed our yard considerably last night.

Butterfly numbers were down to two this afternoon. The orange sulphur spent its time going from one sunny spot to another and basking in the sun.

It stayed near the barn where the radiant heat added to that of the direct sunlight. The butterfly also angled its body to receive maximum heat. This angled position is called lateral basking.

The other butterfly, a painted lady, preferred the white asters where it basked with its wings open. This position is called dorsal basking.

I sit here looking out the picture window at the backyard, wondering where the warm weather went and if I might see anymore butterflies before winter.

  2. I’m ready to see that again for real. They say we might see a good old fashioned January thaw next week, but I’d bet we’ll pay for it if we do. Stay warm!
