Your letter to the bugman:  Amazing how much ants can carry. And I suspect this was light for it! Do ants paralyze their quarry, or would this one be dead?  I feel bad about the spider, but grateful the ants get to eat.

Western Black Carpenter Ant with Spider

Dear Cathy,
Based on this BugGuide image, we are pretty certain your ant is a Western Black Carpenter Ant, and according to BugGuide: “Omnivorous – eat honeydew, sap, living and dead insects, etc. Do not eat wood, only nest in it, and usually only after fungi have softened it.”  That said, the curl to the Spider’s legs indicates it was probably dead before the Western Black Carpenter Ant discovered it.

Your letter to the bugman:  We found dozens of these inside the house today. I think they got in when we opened doors, but we’re not sure. They are just under 1/2″ long, brown, and appear to have a 3 section body with wings.
How you want your letter signed:  Is this carpenter ant, or something else?

Carpenter Ant Alate

This does appear to be a reproductive Carpenter Ant alate, and the wing veinage looks like that of this individual on BugGuide, so we believe you are correct.  If you found them in your house, we believe they probably swarmed from inside rather than entering from the outside.

Your letter to the bugman:  For 25 years, on the hotter days through summer, my home  was invaded by lines of ants (medium-sized black, perhaps Argentine) apparently seeking water. The past 2-3 years this has greatly diminished. This year, so far, despite (or perhaps because of) record heat, all I’ve seen are two tiny black ants.  Is this phenomenon widespread in LA?

No Argentine Ants

Hi Keith,
Our jealously has no bounds.  First, we are almost certain the Ants in question are Argentine Ants.  Have you moved to drought tolerant landscaping recently?  Argentine Ants cannot survive without water, and the reason they invade homes during the heat of summer is for both food and water.  Unlike you, we had two Argentine Ant invasions in our own offices just yesterday with 1000s of Ants swarming the cat food.  Our Mount Washington neighborhood is not as lucky as your West Hollywood digs this year, and in talking to our neighbors, they are also experiencing a higher incident of Ant home invasions this year.

Your letter to the bugman —
Hello! I hope you are both well!
I see that you’ve discovered a harvester ant colony, that’s awesome. I also discovered what I believe to be a red-harvester-ant colony in north Texas,  in mid May 2018. Alas, the ant bed is located on the edge of a playground, not good. Warm, windy, dry weather. I found a reference:
I was intrigued by the ants’ use of wood; are they actually shoring up their tunnels, like tiny miners reinforcing their mine? One ant carried what looked like a bird dropping. Mysterious creatures, sadly they are increasingly rare here.
Best wishes!

Harvester Ant carrying more than its weight

Hi Ellen,
Are you the very same Ellen with the great garden in Coryell County?  Alas, that great garden that attracts so many native insects does require irrigation, and you will not find Harvester Ants in areas with irrigation.  Daniel has known about the colony of California Harvester Ants several vacant lots away from the WTB? offices since 1995, even before WTB? was a column in the photocopied zine American Homebody, during the time Daniel was renting a house across from the vacant lots.  At that time there were many more vacant lots and the Ants were often found foraging in the road, but as available housing in Los Angeles becomes more difficult to find, more and more previously unbuildable lots are being developed, and with development comes irrigation.  With irrigation come the invasive Argentine Ants that need the water, and much like gentrification, the Argentine Ants will force out the previous inhabitants, including the California Harvester Ants which are drought tolerant.  That is why Harvester Ants are rare in urban environments that lack natural open space.  Daniel has decided to try to get the Santa Monica Mountains Conservancy to purchase some of those vacant lots just to preserve the Harvester Ant colony along with other creatures that will most likely not survive additional development with landscaping.  Your images are wonderful.  We hope some bug-phobic parents don’t insist that the colony be exterminated because of a child being stung by a Harvester Ant near the playground.  We believe Harvester Ants do blockade their tunnels during the rainy season.    

Harvester Ant Colony

Thank you for the reply! Yes, I live in Coryell County and was visiting Stephenville when I saw the harvester ants. Such fascinating insects. Best wishes in preserving the undeveloped lots.

California Harvester Ants
Location:  Mount Washington, Los Angeles, California

We suspect none of our readers will be as excited about this posting as we are, but we are happy to report that the colony of California Harvester Ants that has been living on a south facing slope in Mount Washington is still present, though perhaps not for long as every available lot in the neighborhood seems to have a “Notice of Intent” sign for a new construction project.  California Harvester Ants are naturally adapted to our Southern California climate and they do not need irrigation to survive, but alas, garden landscaping is responsible for the spread of that scourge, the Argentine Ant, and they have displaced our native Ant species in much of urban Los Angeles.

We also located what we believe to be the back door to the colony right at the edge of the street.

Your letter to the bugman:  Hello Bugman,
After hearing / seeing what I at first thought to be a V8 engine flying around my room – then the ‘engine’ eventually doing the inevitable ‘head butt the window, directly next to the opened one’ (which infact I bee’lieve he almost managed to push open anyway….) early this morning. I spent an hour getting over the shock of what I had just witnessed, I then used your very useful website to identify said visitor / early morning alarm clocks identification. I now know the ‘intruder’ was a fully grown ‘Capenter bee.’  – How lovely.
Quite a few days prior to this, I was visited by a very large flying ant(?) – light brown/yellow in colour and displaying a docile temperament (at first). After foolishly believing it would appreciate a small saucer of water, it took acception to this – took flight, and aimed its self directly at my ‘boat shed’ (that’s Cornish rhyming slang for “face”) with me well and truly in its flight path – it was trying to chew my nose and/or eyes off or out… I’m sure.
It eventually ‘banked’ around and flew out of the door – maybe me running away and screaming like a little school girl, was just too much for ant’y flyie thing ? (The picture was taken of it about to start trying to bite an 8mm rivet head off – for reference, ours; not it’s.)
Anyway; I hope you can help me identify it, it will also help me with the (Southern Vietnam) police report, if we do indeed know the species.
Thanking you in advance, I will look forward to your reply.
With kind regards

Red Tree Dwelling Weaver Ant Alate

Dear Andy,
Your submission is quite entertaining.  We concur that the first visitor you mentioned is a Carpenter Bee, and we believe we have identified your flying Ant as a female alate Red Tree Dwelling Weaver Ant,
Oecophylla smaragdina, thanks to the TermitesandAnts Blogspot where it states:  “Oecophylla smaragdina is a common red tree dwelling weaver ant. The color is not definitive of the species as there are also those which are green. Oecophylla smaragdina are group hunters and individual ants are mostly ineffective against live prey except very small ones. … Oecophylla smaragdina nests can be quite extensive covering several trees over a few acres. These nests are made of leaves woven together with ants’ silk secreted by the larvae. Some workers pulled leaves together while other workers each with a larva in its mandibles ‘glue’ the leaves together, with the ant silk secreted by these larvae, to formed a shelter where the brood are housed.”
