I'm pretty sure I have seen this thing on the forum but can't for the life of me find it! The Satsuma orange tree is being inundated with leaf miners and upon close inspection I found a lot of eggs and tiny little cats. This one has grown enough to see well and before we treat the tree with a systemic, I wanted to know if these guys are friend or foe. It is (sorry) a nasty-looking thing... all gooey and slimy looking.
Any help you can give me would be appreciated. Thanks!
