PlantFiles is getting a new look! Just in time for spring, we're rolling out a new look for the best online plants database. It will also work with your smart phones and mobile devices, so now you can take it with you on garden center visits or botanical garden tours. Questions or comments? Please post them here.
This looks like a giant stink bug to me...there are a bunch of them using my ash tree apparently as a motel...they vary in size somewhat, but most of them are at least an inch long, or longer...I keep trying to run them off, or kill them, but they keep coming back...can someone tell me what they are & why they're here & are they a problem?
Thanks...not to say they've never been here before, but this is the first time I've ever seen them. Could they be new around here, possibly? There's been as many as a few dozen on the tree at one time. When you say they feed on woodland plants, what does that mean, as I've not noticed them eating the ash tree they stay on. Also, what does "True Bug category" mean?
The adult bugs may have picked your trees to lay their eggs. Leaf-footed bugs are everywhere really. They are even up here where I live, which is Upstate New York. What I meant by saying woodland plants was any plants and/or trees that live in wooded areas or even just outside. They usually don't eat garden plants. True Bugs are a category of bugs and beetles that are completely "true". They are called the Hemiptera order of insects. The defining feature of hemipterans is their possession of mouthparts where the mandibles and maxillae are put within a modified labium to form a "beak" or "rostrum", called a proboscis, which is capable of piercing tissues (usually plant tissues) and sucking out the liquids – typically sap. That's why they are on your trees. I hope this cleared everything up for you . :)
