Hi! I live in Florida and I just noticed a new bug in my green beans. It's lime green, spikes down the back of it, 6 legs, probably half the size of a pinky nail (or more), no wings. Any ideas?

Hey Julie, welcome to garden.org Here's the link to the University of Florida Bug ID page where the scientists will be able to tell you what that bug is.

I've never seen one of those before, so please do come back and tell us what it is?

Btw, if you would complete your personal profile with your city and county, it makes it easier for people to answer questions in future. (just click on the little person icon in the blue sidebar to the left)

Looks like some sort of leaf hopper?

It does, Deb but now looking at the pictures again, I don't see any holes or damage to the leaves.

Julie, is this bug actually doing any damage? Are there holes or chewed edges on any of the bean plants?

It's a buffalo treehopper nymph. If they're bothering the beans, don't know if they would but they do feed on plants, they wouldn't be chewing holes as they don't have chewing mouthparts.

That certainly is interesting looking!

Welcome to Garden.org, @Julie6556

Wow! Thank you all for your fast replies! I believe it is a buffalo treehopper nymph. I just googled it and it looks just like this little guy! I found 2 of them on the beans. I check my plants several times a day so I don't know if it was too soon for him to do damage but my leaves are in great shape.

So.... They are a bit destructive.....

A buffalo treehopper wouldn't be able to do that because it doesn't have the right mouthparts for chewing, it sucks the juices out of a plant with piercing-sucking mouthparts. So you have a different culprit there, the neat semi-circles are reminiscent of what a leaf-cutter bee does.

Oh dear... More pests... Lol. Do the bees harm the plant in any other way aside from eating the leaves?

They take away the semi-circles of leaf to use in their nests. Unless they take a lot of leaf it won't hurt the plant much - a lot of leaf missing would mean the leaves can't photosynthesize as much which could reduce growth. One suggestion I've seen if they start taking too much (I've never had them myself) is to cover the row with Remay or something similar that prevents them from accessing the plants for the period of time they're active.
