Looks like a very small stink bug.

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.

Subject: Leaf Beetle?

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.

Subject: More kissing bugs?
Location: Pennsylvania

Hi,
I sent a photo earlier today of a bug to see if it was a kissing bug. Here are a couple more photos. There are dozens of these guys all around my house. If you could help me identify them I would appreciate it. I’m terrified that they are deadly kissing bugs!
There are a bunch of these on the screens outside my house. I live in the suburbs of Philadelphia. I have occasionally found them inside. Some are bigger without the red markings, but up too high so I can’t get a good photo. If it is a kissing bug, how worried should I be. And how should I get rid of them? Thanks!
Thanks for your help!

Mating Boxelder Bugs

Mating Boxelder Bugs

Dear Michelle,
You have nothing to fear from these mating Eastern Boxelder Bugs.  They are harmless, though they can pose a considerable nuisance when they form large aggregations on exterior walls of homes.  They tend to favor walls with light colors and sunny exposures, exactly like those in your image.  You may or may not be amused that Eastern Boxelder Bugs are also known as Democrat Bugs because of the large aggregations they form.  Seems they are making a timely appearance with your Pennsylvania primary election occurring next week.

Thank you so much!! I really appreciate you getting back to me!

This insect survives all winter and gathers by the hundreds in clusters on the south side of my home, in the sun. They find their way inside my home and I release them. Are they harmful and how can I get them to leave the area without killing them?!
Thank you! Kevin

Democrat Bug

Democrat Bug

Dear Kevin,
This is an Eastern Boxelder Bug,
Boisea trivittata, but we are really amused at its other common name, Democrat Bug, so we are postdating your submission to go live the day before the primary elections Tuesday to remind our readers to get out and vote.  Eastern Boxelder Bugs hibernate over the winter, and they will emerge on sunny days exactly as you describe.  Eastern Boxelder Bugs are benign, though they can become a nuisance when they appear in great numbers, especially if they decide to hibernate indoors.  If you are not troubled with their appearance, you can safely allow them to sun themselves as they pose no threat to you, your pets or your home, nor do they damage plants as they feed primarily on seeds.  The common name Democrat Bug, as well as names like Populist Bug and Politician Bug, refers to the communal habits of the Boxelder Bugs, and in light of the political circus of the 2016 primary season, we will be featuring your submission for the duration of the election season.

Very helpful, thank you for taking the time to respond.

I found the group of orange insects with black spots near water last August, in the Walnut Creek Open Space, California. Later I found an earlier picture of a what must be a close relative of this bug in my files. I don’t know where I found it. That one does not have the spots.
I hope you can tell me what these critters are.

Large Milkweed Bug Nymphs

Large Milkweed Bug Nymphs

Dear Dirk,
We wish you had not cropped your image.  These sure look like Large Milkweed Bug nymphs,
Oncopeltus fasciatus, based on this BugGuide image, and they do appear to be feeding on milkweed pods, but we would love to see more of the plant to try to identify the species of milkweed.  The image you captured earlier is also a True Bug in the suborder Heteroptera, but from there the taxonomies diverge.  The Large Milkweed Bugs are Seed Bugs in the family Lygaeidae and the other is a solitary Western Boxelder Bug nymph, Boisea rubrolineata, in the Scentless Plant Bug family Rhopalidae which you can verify on BugGuide

Hi Daniel
Thank you for identifying these Large Milkweed Bug larvae!  You regretted that my image was cropped and I found a less cropped version, for what it’s worth.

Thanks again.   I really appreciate your response to my query.

Wow Dirk,
We are so excited to get an image that includes the narrow leaf milkweed seed pods and the leaf is also visible.  Las Pilitas Nursery has more wonderful information on the California Narrow Leaf Milkweed, a critical plant in a vibrant ecosystem that we profile in Milkweed Meadow.

Subject: What’s this bug?
Location: Northern California foothills
November 29, 2015 5:18 pm
I live in the California Gold Country, halfway between Sacramento and Reno, NV. The elevation here is about 2500 ft. We have been in a prolonged drought, but have recently had a little bit of rain. I have lived in my house for 3 years and never seen these bugs before. About a month ago when the night time temperatures got cooler these bugs appeared on the sunny side of my house. The seem to enjoy sunning themselves but also seem undeterred by temperatures at or slightly below freezing. They particularly gather on window screens and windows. They fly or they run quickly when approached. The are about 1/2 to 1 inch in length and they have some red on their underside. They are very active during the day and I don’t see them after dark. They don’t seem to be doing any damage but there are a growing number of them and I am a bit concerned about them getting into my house and causing a problem. I have seen a few on my neighbor’s house but they seem to prefer my yellow house that gets a lot of sun. Oddly, my cat and dog who typically will play or catch bugs leave these guys alone. Any idea about what they are and should I be concerned? Thanks so much for your assistance.

Western Boxelder Bug

Western Boxelder Bug

Hi Barbara,
This is a Western Boxelder Bug,
Boisea rubrolineata, and it is considered a benign creature though they are prone to forming large aggregations that can become a nuisance if they are plentiful or if they enter the home.  The behavior you describe is very common for the species.  When weather cools down, they will enter homes to hibernate, but they will not cause you or your home any damage.

Hi Daniel,
Thanks so much! Glad to know I can let them be without worrying that they are eating my home.  Have a wonderful day!
Barbara
