Having grown up in Maine (whose “state bird” is the black fly) and currently living in Florida (whose “state bird” is the mosquito) I have plenty of bug experience.
One odd thing I’ve noticed about the bugs around my house is that that they all seem to have different preferred targets. The mosquitoes, which dominate my backyard, are savage ankle and back biters. On the plus side, as long as I spray my ankles and the back of my shirt, I seem to be bug proof.
The bugs out front only attack my face and ears, so spraying my face is enough when working out front. Of course, if I am moving about, I need to do do more coverage.
The bugs in the park attack everywhere.
I can only infer that bugs have some sort of treaty system going based on the location of the victim. Around my house, the back bugs get ankles and backs. The front bugs get the face. Presumably the park is public domain for us and the bugs.
