I have queens, all with eggs, and I'm not 100% sure they are mated. How can I tell if they are?

I often hear that fertile queens are more likely to have their eggs in a neat little pile, while unfertile queens will leave them lying around.
What if its just one egg that is not in a pile? Also what would be a neat little pile?
There is no 100% guaranteed way to tell if a queen has mated, but you can look for signals. Did you find them with or without wings? Queens with their wings still attached have a lower chance of having mated but it doesn't mean they aren't fertile. When were the eggs laid? You should see development into larvae around 1-2 weeks depending on the species. Fertile queens also tend to clean the tips of their gasters quite often.

Tetramorium Immigran (8 Workers)
Myrmica Queen (Not 100% on species)
Formica Subsericea (No workers)
A pile would be if all the eggs were clumped closely together

What about when the eggs hatch? Will they even hatch?
Sometimes queens lay trophic eggs, which they eat before hatching. However, if an infertile queen lives long enough, her eggs will grow into males.
I think that's what they meant... I'm guilty of using them as synonyms too

Oops, sorry
Probably over 98% of queens are fertile unless they have some genetic deformity or something. What you should be asking is if the queens are mated.
Ah ok, I meant mated then, not fertile

Interesting....I did not know that

I actually find one of the best indicators is caring for the eggs, constantly licking them, as many queens will lay a pile of eggs, and just ignore it. All of those seem to be unmated.
Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies.
However, I went back to the Sierras, and restarted my collection, which is now as follows:
Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

that's an older picture, but do you think it's mated?

Wouldn't gravid be a better term?
Gravid means with eggs. Unmated queens can still lay eggs. I can't guess whether that queen you have there is mated, I would have to observe for a few days.

This is a weird word, but would impregnated be a good term instead of mated? XD
Well, everyone else here brought up good points. Basically some signs:
Sometiimes, you can encourage laying by providing better conditions, such as using a heating cable if your queen doesn't get enough heat and providing adequate humidity and giving your queens a lot of space.

Well, everyone else here brought up good points. Basically some signs:
- Wingless: not always a reliable sign, I've had plenty of queens I found with wings found colonies.
- Licking the tip of their gaster: They curl up, as if to lay an egg. I like to think of this as practice.
- Settling down: A lot of mated queens will settle down quicker, but this isn't actually a very reliable sign, as most Camponotus queens are very active in the first few days, and eventually unmated queens will also settle down.
- Egg piles: In the rare occurance unmated queens lay, they will usually eat the piles (some sensitive queens do this though) or lay eggs but not organize them. I have dealt with these queens before

Thx for the help! Thankfully, all my queens so far have laid eggs.
I will look out for them licking the tip of their gastor.
Or perhaps inseminated? I always feel like ‘unmated’ is such a casual and non scientific term.This is a weird word, but would impregnated be a good term instead of mated? XDGravid means with eggs.
