Please, the mosquitoes alone will ruin it for him unless he locks himself indoors. I went to bike week in Daytona once, that's not even that far into the summer, and ended up being sucked dry by those prehistoric bastards.
"Robin, Beth rescued 15 spiders from a Cuban with a can of Raid, she's a saint. We are starting Bianca's Eight Legged Friends down in Florida please send a contribution. You will get right into heaven."
This is an Oleander Caterpillar and the other photo of the spider is a banana spider. Both are harmless though you can get a small bite from the spider it's not life threatening. The caterpillar will eventually turn into a black moth with white dots on its wings and a red point on its abdomen. Also harmless.
