ID confirmation

A newly emerged Brown Hawker (I love the exuviae in the foreground). From the shape of the abdomen I would say it was a female.

Very much appreciated Chris,

Very much appreciated Chris, grateful for that confirmation. It was a lovely find with the shuck beside it.

Thanks.

ID Error

Cathal

Please accept my apologies for misleading you, lets just say I was fooled by the brownness of the dragonfly.

Just shows you never assume.

Having looked more closely I have to agree with Brian's observations and agree it's a Common Hawker.

Sorry again, Chris

No worries Chris, it was me

No worries Chris, it was me who started the brown hawker idea, it was a suggestion at best by someone else who knows a lot about some types of insects.

It did cross my mind that this might be common hawker but I sort of wanted it to be a brown hawker as it would be my first record of it.

The yellow costa are a good observation by Syrphus. Edit-I just made a big assumption that the stark pale areas of colour on the side of the thorax were the costa, I'm not sure if I am right, can you tell me where the costa actuually are? I am only familiar with the term from moth wings.

Cheers Chris,

Cathal.

Costa

The costa is the leading edge of the forewing. It varies in colour from species to species.

Oh dear......

Thanks for that Chris, Ive definitely read that before in relation to moths, but not all things stick so well in my head, it was STIGMA I was thinking about, re moth wings, not costa, sorry for the confusion, bear with me, I need to make less assumptions, and definitely less guesses!!!!

Is there a name for the big pale patches on the side of the thorax, having looked at the common hawker I posted earlier, the patches I am referring to are actually pale blue anyway, not yellow.

Thanks again for the help,

Cathal.

Oh Dear

Cathal, I'm guilty of the same, I must make it a New Year's resolution to make less assumptions, they always catch you out.

I'm not aware of the stripes having a designated name. I would just refer to then as "side thoracic stripes".

Have a great day tomorrow.

Regards Chris

Thanks Chris, hope you are

Thanks Chris,
hope you are enjoying your day also. Extremely windy here right now, proper winter weather. The sea is pretty impressive today.

I stuck in another image I found Limnoporus, not that I doubt the ID, just it might help anyone interested.

Do you know the Garron Plateau yourself? Have you recorded there?

Thanks,

Cathal.

Garron

Yes I have been to the Garron but not for a while. Its a wonderful boggy area with some nice lakes. Had one of my first encounters with Aeshna juncea (a newly emerged one like yours) when I was there doing bird surveys in the 1980s.

Hi Limnoporus, Is anyone

Hi Limnoporus,
Is anyone looking at the birdlife on the Garron Plateau at all now?

Some interesting species are doing ok there. I wonder has there been any change in the grouse numbers since the time you were surveying?

I suppose they do fluctuate a bit from year to year, I think I am seeing a lot of heather beetle larvae?

I might put up a photo to confirm the larva.

The more I look up there, the more I find, hoping to record some moths and other things not recorded there yet. It is full of lizards!

Cathal.

Hi Limnoporus,

I havent supplied any dragonfly records anywhere yet. Have been putting a fair bit of effort into recording butterflies, moths and beetles but I'll start to report dragonflies too from now on.

Will do, thanks,

Cathal.

Female Moorland/Common Hawker.

I'm rather late coming into this, but I agree that it is A. juncea - it's also a female as suggested in Chris' original comment (the ovipositor can just about be made out in the first photo - and can be seen on the shed skin or exuviae - though of course it can only be assumed that the exuviae is from this dragonfly!).

Thanks Roy, I'd say the

Thanks Roy,

I'd say the chances are pretty good that it belongs to this insect. It wasnt a set up, thats how I found it, was a nice find.

Thanks,

Cathal.

The chances are very good!

The dragonfly in the photo is not yet in a state in which it would be able to fly anywhere, so the larval skin that it emerged from will definitely be somewhere nearby.
It's not uncommon to find several dragonflies emerging in the same spot over the course of a few days (or even at the same time) though - which is why I said that i couldn't be certain the exuviae was from this dragonfly (there could potentially be other exuviae just out of shot!
