The female dragonfly is called?

The female dragonfly is also called a damselfly, according to this source: https://en.wikipedia.org/wiki/Damselfly

Update, it's a separate fly with wings normally folded up. See my later answer (satguru, moderator).

I have never heard of a female dragonfly having any particular name.
The damselfly is a totally different species from the dragonfly.
Damselflies are small relatives os damselflies and feed on smaller insects. Their eyes do not cover their heads, and they rest with their wings above their bodies, rather like butterflies, while dragonflies rest with their wings straight out beside the body.
There are 27 species of dragonfly and 17 species of damselfly in the British Isles.

I thought that when I found this particular reference. Certainly in Britain a damselfly is different from a dragonfly, but I wasn't sure if this was the case on the other side of the pond. If the website information I have provided is inaccurate, please accept my humble apologies, though it was only 6.00am when I posted that answer, and I had only been awake a few minutes! Next time I will research the question more thoroughly, instead of just briefly clicking through Google and posting the first thing I come across which looks like a good answer! Now, I'm going back to bed!

Norwich - Only just re-read my post. I sound like a head mistress! I really am sorry. You need sleep and I'm suffering from World Cupitis. No more!! Thank Goodness!

No need to apologize, Siskin, but thank you for your kind words! Having re-checked, I agree with you - A dragonfly, regardless of its sex (can I use that word on here, McG?) is still a dragonfly!

It's a queen. https://researchmaniacs.com/Animals/Female/What-is-a-female-Dragonfly-called.html
