4/2/18 Queen on Mt. Tamalpais, CA


Best Answer YsTheAnt , April 3 2018 - 8:30 PM

Limeoptum, probably occidentale, they are the most common. Maybe it is luctosum, but I doubt it. The brood pile gives it away, this species lays a huge first batch of brood. Go to the full post

I caught this queen last year but I was never able to identify her properly before a Linepithema invasion of my house resulted in her death. As the time of year I caught her is approaching, I'm going to try to catch more of her species in the same location once we get a warm spell.

 

1. Location (on a map) of collection: Mt. Tamalpais
2. Date of collection: April 20, 2017.
3. Habitat of collection: Edge of chaparral that bordered open grassy mountainsides.
4. Length (from head to gaster): Unsure, I lost her measurements. I have a fuzzy picture of her next to a 12mm Formica queen, and she looks ever so slightly smaller. 
5. Color, hue, pattern and texture: Very dark brown to black, slightly lighter legs. Very smooth overall.
6. Distinguishing characteristics: Very shiny, quick and alert. 
7. Distinguishing behavior: No cocoons for the pupae.
8. Nest description: Unknown, she was the only ant I saw in that spot. 

9. Nuptial flight time and date: ~3pm, April 20, 2017.

Liometopum. Drew or the other experienced CA anters will know the species.
