Queen Ant in the winter?

[JPSMedeiros]

Hello, today when watching some TV an insect with wings landed on the TV, I realised that it was a Queen Ant, don't know the species but it was. I ran to take my test tube, I was not prepared since it's winter here(I live in Brazil) , when I came back she was gone.
I would like to know if you guys know if that's normal, to see a queen ant in the winter. Maybe because here is a tropical place and it's always hot, don't know for sure. Other little thing, I haven't seen a Queen in a long time and very probabily she was lost for some reason and that would probably result on she not being fertile.

I'm not an expert at this, but it may have been a carpenter ant queen. Especially if it is kind of black, or black and red. Probably meaning there is a carpenter ant colony in the wood of your house. I could be wrong, but that's what I think.

Ants will fly when it is warm, so in consistently warm or tropical environments, they might fly in summer and winter. Usually, flights are timed more around rainfall.
