Janet, you ask a lot of questions! That must be how you get so smart!
I didn't know drgaonflies would angle their bodies like that for warming or cooling purposes. Butterflies do the same thing, but not nearly as dramatically!
The property behind me has 6 acres of wetlands so mosquitoes are always going to be a problem. And I have a huge collection of bromeliads so I'm sure that doesn't help. My county doesn't give too many specifics on what they're actually spraying but I did read that they use Permethrin as a barrier spray. I bet they also use the bacterial sprays which is bad news for my caterpillars. Here's the FAQ page for the county's mosquito spraying program:

I just saw in the news that some of our sentinel chickens tested positive for West Nile Virus so that always makes everyone crazy and you get idiots who go out in their yards and poison everything.
