I tried to get as clear of a shot as I could but the lens on my camera isn't really for macro shots. I found a few of these little buggers on a cucumber plant I was getting ready to replant and I have no idea what they are! This is the biggest one but there were much smaller ones that looked like immature ones. I also noted white spots on the tops of the leaves and very small black spots on the bottom. Any help would be appreciated. Thanks =D
