I found these guys in my home. I have lived here for ten years and have never seen them before. I have taken an insect identification class before, but I am not experienced enough to figure this out. It looks like a Hemiptera of some sort. It’s about a millimeter long and it is pretty difficult to get a picture of it. It’s winter here in Southern California, and I am in the high desert. Could you please help? I don’t think it is the brown marmorated stink bug because it doesn’t have true bug characteristics and there’s no odor. I suspect it is coming in through a crack somewhere for warmth, but who knows what it is. I don’t think it is butting me or my animals because it doesn’t have apparent piercing/sucking mouthparts. Please help.

Dear Cass,
Though your photo is blurry, your immature Hemipteran closely resembles the bugs in this photo from our archives that we tentatively identified as Dirt Colored Seed Bug nymphs, though there is some question that they might be Chinch Bug nymphs.

Can you help me identify what this bug is. I just showed up and there are hundreds of them on my front porch. They don’t bite but are a bother.

Dirt Colored Seed Bug:  Rhyparochromus vulgaris

Dirt Colored Seed Bug: Rhyparochromus vulgaris

Hi Jason,
Whenever a person is suddenly troubled with large numbers of small insects that we don’t recognize, we suspect an invasive, exotic species, and in your instance, our instincts were correct.  This is a Dirt Colored Seed Bug,
Rhyparochromus vulgaris, and it is a relatively recent introduction to the Pacific Northwest.  According to BugGuide, it is:  “native to Europe, recently introduced to NA (Seattle, WA area)” and “earliest NA record: WA 2001; since 2003, large congregations have been reported in nw. WA; expected to spread to BC.”  BugGuide also mentions that these Dirt Colored Seed Bugs are found:  “on the ground and on tree trunks; tends to congregate around buildings late in the season seeking shelter.”  The government shutdown has negatively impacted our ability to link to any information provided by the Department of Agriculture (USDA) as they are deemed not essential at this time.  British Bugs has some information, including:  “The London records are from dry grasslands; this species seems much more of a generalist than R. pini, which is mainly found on heathland in the south-east.  Adults overwinter, mating in the spring. The new generation is complete from late July onwards.”  Now we are wondering if the Dirt Colored Seed Bug nymphs from Montana we posted some time back might be  Rhyparochromus vulgaris.

Large Milkweed Bug

This is a magnificent photo of a Large Milkweed Bug, Oncopeltus fasciatus, preparing for flight.  When resting, the wings cover the abdomen.  Large Milkweed Bugs are True Bugs in the Seed Bug family.  We did find a photo on BugGuide that is similar, but not as nice as your photo.

Thank you kindly for finding about this bug and for the compliment about the photo. I love nature and I may have to pick your brain again soon!

Hi Daniel,
Here are two Milkweed Bugs that look as though they are kissing. Below them is a nymph. Are they kissing, protecting the nymph from my prying lens, or something altogether different? They sat like this for quite some time.

Hi Anna,
We have no idea what these Large Milkweed Bugs are doing, but it is still a very lovely and interesting photo.  Perhaps one of our readers will know what is going on.

Mediterranean Seed Bug

Mediterranean Seed Bug

Dear Scott,
You have Mediterranean Seed Bugs,
Xanthochilus saturnius, an invasive, exotic species that is, according to BugGuide:  “native to Europe and the Mediterranean, adventive in NA (WA-CA) and now locally abundant” and “can be very abundant in grass seed fields in so. OR.”  It was first reported in North America in 1994.

Great thanks…. So how do i get rid of them!!!

We do not provide extermination advice, and we tried unsuccessfully to find an agricultural fact sheet on them.
