Flowers Bloom in HEAT

It is evening here in Central NY State and the temperature with heat index is 34ºC or 94ºF
these flowers are not at all the blip I aimed for today. This morning I saw an unusual caterpillar chewing on a Queen Anne's Lace bud. I could not identify it and thought I would ask Deb or another bug blipper. The ones I took were not clear enough to post. So, I thought I would try later on.
Now it is "later on' & too unbearably hot to be out searching for an errant caterpillar who looks like a folded green leaf, by the way.
It had hacked the little bud off and disappeared by the time I returned for a second try.
So, I whipped around the garden, got stung by a roving beetle, and just aimed at the first blooming flowers I spied. Coneflowers can tolerate drought and heat.
Way too hot for humans to even think. It is @ 78º inside the house right now.
The weather people promise rain and thunderstorms tomorrow. PLEASE?
