This is Lasius ,what I found today (in churchyard) (today 9.april 2007) ,but I don ´t know ,what is it. It could not be Lasius flavus ,because flavus is more gray color and this ant is in really all yellow. This queen is 9 mm long. What is this?
I just found something similar last week. My first guess was also L. flavus. If we would know the swarming time of different Lasius sp., we would end up less potential species.
In a hungarian forum I get another possible identification for _my_ ant: Prenolepis nitens which is a kind of honey ant. It is swarming in early spring. The idea came from an ant expert working in a university. I now searching the net (and at home I will search my books) for Prenolepis. So far it sounds good.
What is your opinion?
All signs shows it is Prenolepis nitens. Prenolepsis has 6 teeth in its mandible (Lasius has more than 6) it also has a heart shaped forward pointed petiole. And the early swarming time is also matching (I found mine 1th of April).
I also has some image from mine. Skippy, you can check the similarities.
