Hi bugman!
I just noticed thousands of these guys hanging out in my backyard mostly around decorative grass and dry whirlybirds. They vary in size and amount of yellow and seem to like to clump together.

Boxelder Bug Nymphs

Boxelder Bug Nymphs

Dear Lisa M,
These are immature Eastern Boxelder Bugs,
Boisea trivittata.  Adults are winged.  Both adults and nymphs form large aggregations leading to popular names like Democrat Bugs or Populist Bugs.  According to BugGuide they feed on the seeds of the following trees:  “Acer grandidentatum (Bigtooth Maple), A. negundo (Boxelder), A. saccharinum (Silver Maple), A. buergerianum (Trident Maple), and Sapindus saponaria (Soapberry).”  You must have a nearby maple tree.  Boxelder Bugs do not harm the trees and they are not dangerous, but they can be a nuisance if they are too plentiful.

I think these are the babies of a black and red beetle. They have swarmed my echinacea!
Thanks for helping to identify.

Democrat Bugs

Democrat Bugs

Dear Kristen,
These are immature Eastern Boxelder Bug nymphs, not beetles.  They are sometimes called Democrat Bugs because they aggregate in large numbers.

These bugs showed up in our area last year for the first time. It has been suggested that they are box elder bugs, but they do not look like photos of box elder bugs. Can you help ID them?

Mating Bordered Plant Bugs

Mating Bordered Plant Bugs

Dear valleygirl,
These are Bordered Plant Bugs in the genus
Largus, and considering your location, we are relatively confident they are Largus cinctus, a west coast species.  You may refer to BugGuide for additional images of Bordered Plant Bugs.

At first I thought these were beetles, but after a bit of google research I have come to think they are Box Elder Bugs. I found them like this on my window screen (mating?) where they stayed for 2-3 days with little movement.
I was unable to get a photo of the top side (or even see it), but I spotted another one about a week later and after viewing its top side it appeared to be a box elder bug.

Mating Boxelder Bugs

Mating Boxelder Bugs

Dear Anonymous,
A ventral view is not ideal for an exact identification, but the red eyes that are clearly visible on the pair in your image and in this BugGuide image are a very strong indication that they are mating Boxelder Bugs.

Flying, lots of them, near a newly built deck. Landing on skin which caused a bit of irritation.
Looks like a very small stink bug.
Help!

Tarnished Plant Bug

Tarnished Plant Bug

Dear NoMoBugs,
We located a matching image on FlickR that is identified as Lygus lineolaris and when we researched that name on BugGuide, we learned it is the Tarnished Plant Bug.  Earlier today we posted a very similar image from California that we believe is a Western Tarnished Plant Bug.

We have an infestation of hundreds of beetles that are on our ash tree and lilac bush underneath it. They are very active in the late afternoon in the high 80’s and the ash tree is being defoliated. They are also working out on the lilac bush and it is becoming sickly looking. Looking at pictures they seem to resemble a leaf beetle but I’m no bug person. Can you help?

Plant Bug: Possibly Orthops scutellatus

Plant Bug: Possibly Western Tarnished Plant Bug

Dear Larry,
These are definitely NOT Beetles.  We believe they are Plant Bugs in the family Miridae.  It resembles
Orthops scutellatus based on this and other BugGuide images, but that species feeds on carrots and other Umbelliferae according to BugGuide.  Perhaps an even better match is the Western Tarnished Plant Bug, Lygus hesperus, which is also pictured on BugGuide.  According to BugGuide, it is “Widespread in the western North America in agricultural and relatively low elevation regions extending from southern BC to northern Mexico.”

It seems to be the Western Tarnished Plant Bug, Lygus hesperus.
Thanks so much for your help.  They seemed to like my ash tree, and lilac and are leaving my strawberries alone for now.
