Guess who just landed on me while I had a shower?

A light brown Lasius queen.

From the nuptial flight calender, this is either a parasitic Lasius umbratus or a pest species, Lasius brunneus. 

The queen is not dark enough to be another Lasius niger. 

I will have to take better pictures tomorrow and look at my ID keys.

I actually do not need another Lasius colony, and would not be confident enough to keep a pest species (Lasius brunneus will take over your house). 

However, if this is Lasius umbratus, I might try a parasitic founding or at least try and see if brood from my Lasius niger colony can jumpstart this colony (I will not let a parasitic queen lose on my Lasius niger colony). 

But If I try this, I will have to do a bit more research on how you go about it.

Lasius emarginatus

You sure?

Here in Germany, they should start flying at the end of July. That is a month early.

I find these Lasius hard to tell apart, I will have to have a look at the ID keys when I come home from work.

 

In any case, sadly, emarginatus is also considered a pest species, so if it is that, I might not keep her.

I would point out that the old records about what time of year what went on, is something that is not as reliable as it used to be. Time frames related to typical temperatures and moisture levels at a time of year are shifting. And the creatures reacting to environmental conditions rather than a hard clock, are shifting with it.
