1) I find this bug very interesting; I saw it flying around once, and then saw it again dead. Its body is bright orange, it has translucent wings, and has an arched back, and long antennae.
Any info about it besides its name would also be appreciated.

2) spider - just curious what it is, I've gotten two spider bites that really swelled up, could it be from this? Appears to have long 'teeth' (what are those?).



Also, I don't have a pic, but there is a bug which I see around alot that it a bright yellow/green with black spots, round body shape, kind of cute looking. Do you know it?
