My dogs go after flies sometimes. They used to go nuts if one was in the house (especially Smokey). A bit lazy and old now, they don't really care as much lol. I've never seen them go after any other bugs, except a few that resemble flies such as bees.

As a sidenote, I've always wanted to see fireflies! We don't have them here. See, as a child I was bug obsessed. That's what I did all summer was catch bugs. My favorites are the praying mantis. I still like bugs, but I'm not a fan of spiders...or mosquitos..ok mostly I'd just rather not have any unknown critters crawling on me.

We went camping this weekend and out of boredom I caught a couple these green bugs. Had kinda long bodies, and big lacey wings. I thought they were cool until I discovered the smell. Nasty! I didn't think something that small could smell so awful...I bet my hands still stink....
