1. I have found this outside near my apartments around 7:15 - 7:30
2. 8/21/22
3. Urban area is the habitat
4. length: around 1.5 centimeters
5. One is bright reddish orange near the middle plus the head and other wise brownish, and the other one is all brownish
6. Behavior both were a bit active when I first put them in, then calmed down slowly
7. I have a feeling that one of them is semi-parasitic, but I don't really know

ok, but i put them in a dark place, and is it ok if i take them out again?

[Manitobant]

Yes

The all brownish one is a claustral Lasius species, probably neoniger at this time of year. Will need more/better pictures of the one with the red head for an ID, but possibly a parasite sp.

Ok thanks

From my very limited knowledge and experiece I found out this:

Semi-parasitic Lasius sp. tend to be very active, to the point that they make you feel bad for putting them in a test tube.
Their head is larger or equal in width with their thorax.
Their gaster is usually not as big and bulky as claustral species.
Claustral Lasius - big round gaster + thorax is larger than their head. Head is generally smaller.
Semi-parasitic Lasius - smaller and more streamlined gaster + thorax = head. Head is larger with large mandibles.


They both seem claustral Lasius to me, specially if they both calmed down.
My semi-parasitic queen ( L. fuliginosus I believe) was Speedy Gonzales until I gave her workers to adopt.
