Subject: What’s this bug?

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

Dear Kathleen,
The Eastern Boxelder Bug is not considered a pest species, but when they are present in large aggregations, many folks consider them to be a nuisance, especially when they enter homes to hibernate with the onset of colder weather.

Hi! So, I had just picked up my nephew from Kindergarten, when we spotted this little guy scurrying around on the sidewalk. My nephew thought it was the coolest thing, but when he asked me what it was, I couldn’t give him an answer. I would love to know what this is, because once he finds out, he’ll want to look up videos of it on YouTube lol. Thanks a bunch for your time!

Red Shouldered Bug

Red Shouldered Bug

Dear Auntie Alex,
The Red Shouldered Bug,
Jadera haematoloma, is also known as the Goldenrain Tree Bug because that common landscaping tree produces seeds eaten by the Red Shouldered Bug.  This species often forms large aggregations when feeding.

We think these may be stink bugs, but we are unsure

Scentless Plant Bugs

Scentless Plant Bugs

Dear Richard,
Though they are not Stink Bugs, these Scentless Plant Bugs in the family Rhopalidae are classified in the same order as Stink Bugs.  Your individuals are
Niesthrea louisianica, a species without a common name.  They are frequently found feeding on Rose of Sharon and related plants.  According to BugGuide, they are “an important biocontrol agent of velvetleaf (Abutilon theophrasti).”

Bordered Plant Bug

Bordered Plant Bug

Dear Catherine,
You have submitted an image of a Bordered Plant Bug,
Largus californicus, a true bug, not a beetle.  According to BugGuide, they feed on:  “Mostly plants (flowers, leaves, fruit) from a range of families, with a preference for Lupines. L. californicus is not considered a “pest species” of economic importance.”

Dear Daniel,
Thank you so much for identifying this little guy.  That is so interesting.  I shared with my fellow bug hiking mates too.  Terrific that you do this!  Catherine

You are most welcome.  Though we have an international following, we are a local resource for you in Los Angeles.  We can see the Griffith Observatory from our offices in quaint Mount Washington in the hills of Northeast Los Angeles.
