I've seen one winged queen and a few virgin queens just inside the nest entrances in Liverpool just now. Don't know if there's definitely going to be a flight today but it's likely in the next few days so keep your eyes peeled.
Not sure what species they are, probably L. niger though several of the colonies are at the base of tree trunks and the workers look like they have lighter coloured thoraxes.
:/ I have for the first time seen aletes fly off their nest into the sky both Lasius niger and Formica cunicularia aletes were walking around their nest entrances but I've only seen niger fly off today.
I'll surely do a tour of the house outside tomorrow morning to find queens
There's a Lasius niger flight going on right now. Collected eight queens, I'll probably keep a few for myself and perhaps sell the others cheaply once they've got nice sized colonies going. No Lasius flavus, unfortunately.
Edit: Decided to keep three and let the others go. I "plant" them in flower pots that aren't occupied by other ants in the hopes that they can establish themselves there.
Here's one of the queens I decided to keep. She's much calmer now that she's no longer flying or running around to flee the many predators that gather during nuptial flights. Hopefully she'll dig before long and start a colony of her own.
My mum was wondering what would happen to the young drones and queens being captured by workers on the ground, so I explained they'd get eaten by the rival colonies. Soon she was going around helping them get to safety, haha. That sort of behaviour isn't allowed in our garden!
