Is lasius flavus polygynous?
Nests can be founded by groups of queens or by single queens, but established nests normally have only a single queen. In dense populations some nests can be polygynous and a few polydomous spreading over two or more mounds (Steinmeyer et al 2012).
Where do lasius Umbratus live?
Widespread over both Eurasia and North America. In eastern North America Lasius umbratus occurs from Nova Scotia south to the Gulf States. Westward, umbratus is abundant through North Dakota, as evidenced by the large numbers of collections made in many localities in that state by G. C. Wheeler and his students.
Does lasius Niger have majors?
Lasius niger do not create a major caste. Nests underground, commonly under stones, but also in rotten wood, and under roots. Nectar, small insects such as codling moth larvae, fruit, will farm aphids, cockroaches, beetles.
Is lasius Niger invasive?

Can lasius flavus have multiple queens?
Lasius flavus is a fully claustral species, able to form new societies with a single queen. But it is very common for the queens to huddle up together in what’s called pleometrosis, multiple founding queens.
How big do lasius flavus colonies get?
Colony sizes of the two species are listed in the literature as a few hundred to a few thousand for F. lemani and up to 100 000 workers for L. flavus (Douwes et al., 2012).
How big is a lasius Niger queen?
Worker length: 3.4 – 5 mm, male length: 3.5 – 4.7 mm, queen length: 8 – 9 mm. Workers (non-reproductive females) are blackish-brown in colour and covered in small hairs.
Can black garden ants have multiple queens?

What ants have super majors?
morrisi colony, a species of the Pheidole genus, with unexpected supersoldier-like features. The discovery suggested Pheidole species share a developmental origin when it comes to supersoldiers, since the eight species with this type of ants are found only in the deserts in southwest America and northern Mexico.

Where is Lasius umbratus found in North America?

What is the difference between Lasius flavus and Lasius umbratus?
Unlike the common yellow ant Lasius flavus (Fabricius), L. umbratus workers have numerous erect hairs on their scapes and tibia. Queens are reddish brown and have heads that are broader than the maximum width of the alitrunk.
Is Lasius umbratus a parasitic ant?
Lasius umbratus is a parasitic ant. The queens of this species seek out a Lasius niger worker ant, to first kill in order to gain the worker ant’s scent and then to discreetly sneak inside a Lasius niger nest.
Where is umbratus found in North Dakota?
Westward, umbratus is abundant through North Dakota, as evidenced by the large numbers of collections made in many localities in that state by G. C. Wheeler and his students. It appears to be relatively common in the southern Rockies, but sparse to absent over most of the rest of western North America. Latitudinal Range: 65.256706° to 31.156163°.
