Biting / Stinging Ant? - Cephalonomia

Biting / Stinging Ant? - Cephalonomia
New York, New York County, New York, USA
May 20, 2017
Size: 0.16 cm
1. Location = NYC apartment, 3rd floor

2. Size = 0.1 - 0.2 cm

3. They bite or sting, burning and painful, leaving quarter-sized welts that last for at least one week

4. When they die, they curl up into a little ball

5. Seem to come out in the Spring, last year and then again this year

6. Rarely seen, usually only one every few days, though sometimes several in one day if very vigilant

7. This year more often seen on kitchen counter, kitchen island, or bathroom counter, though also seen occasionally on/in toilet, bed, couch. Could be that they are just easier to see on the white counters. Last year saw 3-4 (most I ever saw together) in bedroom going under a baseboard.

8. Do not seem interested in fruit, crumbs, honey, butter, oil, sugar, peanut butter, frying pan grease. One time it appeared one was interested in the dried out milk and coffee on a dirty coffee mug left out. Never before or since seen on my coffee mug. Do not seem interested in my homemade peanut butter and honey borax baits or commercial liquid (Terro brand) ant baits.

9. Do not seem to travel in a "trail" pattern. They just seem to wander

10. Do not seem to travel in groups, just solo

11. No pets in home

12. Plants inside the apartment include giant philodendron, rubber plant,
bamboo, basil

13. Travel to Borneo every other year, but ants first noticed in 2016 and prior trip to Borneo was 2015

14. Hardwood floors in apartment (white oak) with poly-whey floor finish (6 years old)

15. Subflooring in building between floors is filled with sand/debris

16. They seem to like to crawl into my clothing and bite me in there, though they also bite me on my wrists. I have gotten bites on my chest wall (1-2 inches below the clavicle), breast, buttock, calf, thigh, beltline... They tend to bite me more than others in my family, though they do get my kids from time to time and very rarely they bite my husband, who does not get a significant reaction. I put my clothes in the dryer for 20 minutes before getting dressed, but they still manage to get me. Using permethrin body shampoo does not seem to keep them from biting me.

17. I don't think there is any particular time of day they come out. Maybe more in the afternoon?

Thank you fellow Iowans!

Probably C. gallicola
Uniform yellowish color, wingless, and presence of what appear to be dentiform processes on the propodeum indicate this is likely C. gallicola. If you would like confirmation, feel free to contact me about submitting voucher specimens for ID.

The species is found worldwide, associated with stored products. You are seeing these frequently because somewhere (in your building or apartment) is a population of one or more host beetles. Host records for this wasp include Stegobium paniceum, Lasioderma serricorne, Ptinus fur, and Niptus hololeuca.

 
Zimbabwean thumb piano
Wow. Thank you for your insight! You people are brilliant! Indeed a year or two ago, we had an infestation of small brown flying beetles that seemed to be in our pantry & spices: "cigarette beetles"? We threw out old flour & spice products and now have everything in sealed tupperwares. I see them rarely now. Maybe 1-2 every few months. I guess there must be some lingering somewhere or they are in another apartment. I also saw a "spider beetle" a few months ago, but rarely see those either.

I feel embarrassed for not putting two and two together sooner, but: Last fall I was dusting and noticed some dust around a Zimbabwean gourd thumb piano my sister had brought me 15 years ago. I flipped it upside down, and a bunch of "sawdust" as well as 2-3 winged insects (approx 0.6cm size maybe) came out. (I am fairly certain they had wings.) I put them in a jar and took them to my building's exterminator, who sent them to an entomoligist at the museum, and I was told they were "parasitic wasps". No further info. ("You got a parasitic wasp, lady"!) Since I never saw any more of those larger winged insects, I thought they were gone after I threw out the gourd. I didn't realize the tiny wingless insects I have now could be related (I thought they were ants!). Are some members of the species winged and some not? I wonder why they made their home in the gourd? Were they burrowing to make their nest? Are they capable of destroying wood products? Or was it their host that was in the gourd perhaps? I have a lot to learn about these things!

Timeline seems to be: 1. ?cigarette beetle infestation 1-2 years ago, 2. these small ant-like insects Spring 2016 (then they went away and we had no more bites), 3. ?parasitic wasps in gourd Fall 2016, 3. more ant-like insects Spring 2017... not going away this time!

We were on a good stretch of no stings and no bugs seen for 4-5 days, but my son got 4 new bites/stings last night while sleeping on the couch: one on each extremity, oddly enough. I searched the couch immediately (2am) but didn't find any insects. I am curious to learn if they sting defensively or if they target humans too.

Many thanks! Off to do some more reading with the leads you gave me... I am so grateful to have something to go on now!
