Guessing Pyrrhocoridae. Any suggestions? Not sure if male or female. The other similar images are what this one isn't (reproduction behavior). Collected by J. B. Rosell.

new and now established in Utah
This little guy did show up unexpectedly and is now quite well established. I'm keeping informal notes on its southern most and northern most range. Bountiful to the north and Cottonwood Heights to the south. How they got to Utah, no one knows. We did have Tom Henry from the Systematic Entomology Lab at the Smithsonian come to Salt Lake early this summer to collect them.

Huntington Beach CA
Is it common to find these in large groups in Huntington Beach, CA?
If not, how should I proceed?

Also compare...
the specimens observed with Scantius aegyptus. . The length of the adult wing helps to separate the two.

Range extension?
California would be a new location for these in the USA. Do you have a photo of the ones you have for me to see?

Information pamphlet
The Utah Extension office has a nice pamphlet about this species. Apparently it was first found in the USA in Cottonwood Heights, Utah in 2008. I have them in my yard, but they are very restricted to the area under my neighbor's Linden trees. Walk ten feet away and you don't see them at all. I first noticed them in late 2008, but didn't identify them until April 2009.

The website for the pamphlet is:

Hey, Breck!
Hope life has been going well for you. Appreciate the USU link, have to add this pdf to the folder. Enjoy this site, although it can take time away from herpetological pursuits. ; )>

Hi Kerry, I noticed you we
Hi Kerry,

I noticed you were on this site. If all goes well I'll be adding more to this site. I have a seven year old son that is a nature lover. He is pretty consistent in saying that he wants to study animals and lately he says he wants to be an entomologist. I haven't been doing too much with herpetology lately, so delving into insects will be nice.

All the best.

now i'm 100% confident about their identity
Moved from ID Request.

stranded -- nobody to make love to -- thus no Behavior
the only reason i can think of; the do little more indeed

The four specimens...
have been "behavioring" for the last three days. The short wings seemed to indicate an immature. Obviously not (maybe it's teenage experimentation)!. There seems to be a group establishing a colony, still early spring, might not survive summer and competition.

This is a quite gregarious species
who hibernates in large groups, especially under lime tree (Tilia sp.) stumps in its European homeland. They have begun to resume activity for ca. ten days here in the Geneva suburbs - usually this takes place earlier, but we've had a long, cold winter.
At the same place, you're likely to see the first small, mainly red, nymphs from mid April on.

The locale...
will be observed as the year progresses. The population could already be established, and just not noticed before. Thanks for the tips.

mature nymphs look quite different
compare: French colony

those who look like this are all grownups; the epithet apterus says it all -- and anyway nymphs never have the the membranous part on their wingpads

now this must be a Pyrrhocoris [?apterus]
...or i'll eat the server
in Utah, of all places! came with imported merchandise, i guess

infestation of neighborhood
our neighborhood in crawling with them. the lawn looks like it is moving their are so many. there are clumps of thousands of them in one place sometimes. you can watch them mating constantly. i sent a picture to and they positively identified them as a European species, Pyrrhocoris apterus, commonly called a Firebug. i live in the 84124 zip.

I'd venture...
that these have become established in (at least) the Salt Lake metropolitan area. Probably not noticed before because of the ubiquitous Box Elder Bug that is almost anywhere you look, their nymphs are similar in appearance and occur as long as it is not snowing.

I commented on the other image...
I thought it was the European one, too. Is it established here? Do we have native species?

no natives, as far as i know
will check

nope, just a single 100-y.o. NJ record [?intercept]
check emballajem
