Linepithema humile (Argentine ant)   

I had a dying tree containing Liometopum occidentale, but it was cut down, most of the pieces hauled away, and the Argies have raided the remaining pieces of wood for all the tasty termites. I can't imagine the Lios (if they are still around) can survive.

So I think all I have is Linepithema humile. On one positive note, I did find one Prenolepis queen in the spring, but I haven't seen any workers. I can only hope Prenolepis spread into this area.

Check for Strumigenys (native or exotic) in humid areas like lawn clipping, under stones, irrigation systems, etc. There may also be some in drier areas (Strumigenys californica is particularly well known for preferring drier habitats), but I'd try damp spots first. In my experience, Linepithema only go for larger species and don't mess with cryptobiotics, so you should still have some around. Good luck!

OH! I just suddenly remembered I did ONCE find one pale, very very small worker wandering around the room. I thought at first it was an escaped Tetramorium, but it was pale. I didn't catch it and let it wander away. So it's possible there's a cryptic species somewhere. Still, how I wish the Argies would just go away. (The only good thing about them is they aren't RIFA and they might be protecting the house from termites to some degree - not well enough, because there ARE termites, but to some small degree.)

Linepithema are soooooo much worse than any invasive Solenopsis (RIFA, BIFA, HFA, etc.), because while the fire ants are only competitive towards native fire ants, Linepithema are competitive towards everything other than cryptobiotics. Fire ants also don't tend to enter houses or mess with our stuff too much. Linepithema are very rude and will barge right in (hmm, where have I heard this before? *cough*humans*cough*). Also, termite control? Never heard that before, but if anyone's got an invasive that takes care of termites, it's us here in the southeast with our Brachyponera chinensis needle ants that not only specialize in hunting termites, but also force back the Argentines! I'm not saying they're good, quite the contrary, as they are also quite competitive, but pretty much anything is better than Linepithema. Old World and New World Neotropics, keep your Anoplolepis away from us though! I am fully aware they're probably, somehow, worse!

[NickAnter]

I have searched *extensively* in my backyard(and front yard), and only once did I find a single Strumigenys queen in my pool on a warm July evening in 2019. Hypoponera, however, are somewhat more common. You might be able to find them in your grass, I see workers of the dark species foraging above ground all the time. Also once found bright orange H. punctatissima under a plant pot.

 

Here is my revised list, in order of prevalence, including single queens:

1)Linepithema humile

2)Brachymyrmex patagonicus

3)Cardiocondyla mauritanica

4)Pheidole navigans

5)Nylanderia vividula

6)Solenopsis molesta(not molesta, the common one in coastal cali)

7)Solenopsis xyloni

8)Monomorium cf. ergatogyna

9)Solenopsis truncorum

10)Hypoponera cf. opacior

11)Dorymyrmex insanus

12)Hypoponera cf. opaciceps

13)Hypoponera punctatissima

14)Pogonomyrmex californicus

15)Cardiocondyla minutior

16)Pheidole sp.(Single dead queen in spider web)

17)Crematogaster sp.(males in pool)

18)Myrmentoma sp.(male in pool)

19)Tetramorium bicarinatum(single queen)

20)Strumigenys sp. (single alate queen in pool)

 

Edit: Added T. bicarinatum, totally forgot I had one of those.

In my back yard I have...

 

Solenopsis invicta

Brachymyrmex patagonicus

unID’ed species, suspected Lasius

[MrPurpleB]

I have only seen a few species and I probably should get better pics to id them. At one point I thought I has fire ants but it was a Nylanderia.

So far I have seen.

Linepithema Humild
Brachymyrmex patagonicus
Cyphomyrmex Wheeleri
Nylanderia (vivdula?)

Possibly Soleneposis molesta

Argentine Ants don't seem to be very active, maybe since the weather is still fairly cold here.
