Pictures

Lasius Niger ant brood

Some pictures taken some time ago of the Lasius Niger colony. The pictures are mostly of brood as you'll see.

• In the first picture you can see a larvae. This picture allows you to easily see the hair on the sides and the "mouth" area of an ant larvae.

• Here you can see  a size comparison between an ant freshly outside of it's cocoon and a larvae.

• Here you can see the an ant that is out of it's cocoon and almost fully changed color to the dark black/brown that the workers have.

• In this picture you can clearly see a few eggs and somewhere in those eggs the first stage after leaving the cocoon becomes visible.

• And lastly a size comparison between a cocoon and the "hatched" ant.

Unkown queen ant caught

I caught a queen ant in an elevator late at night, I assume it was stuck in there so she might have flown hours before capture (~11pm).

I caught her in the center of Leuven, a city in Belgium. Put her in a test tube setup and took some foto's which are below. Her size is comparable to a Lasius Niger / Lasius Umbratus but she doesn't look like a niger at all and has a way to long abdomen to be an Umbratus (If you look carefully at some of the picture then you can see that her abdomen is nearly the same length as her head and center body combined).

Now I was interested to know what species she is but most importantly whether she is fully or semi clausteral. FYI she already laid eggs and shed most of her wings while in a fully closed test tube setup.
