White Featherlegs

I still have enormous difficulty in separating some of these Blue and White Featherlegs.

Do both varieties co-mingle, or do they keep to themselves?

Don't worry if you have difficulty separating these, to be honest I think that if you decide that they are easy to tell apart you have probably become over confident!
Male (and female) Blue Featherlegs can be white, and male White Featherlegs can have a distinctively blue 'hue'.
With females, Orange Featherlegs can be very similar as well, just to add to the problem.

Unfortunately they can also sometimes all be found along the same rivers - although as you head towards SW France White Featherlegs seem to become increasingly more common in relation to Blue, and White usually seem to be more numerous than Orange, although both regularly occur together. Whether or not there is any hybridisation is another matter - although I'm not aware of it ever having been recorded.

Thanks very much, Roy. I guess I'll just have to carry on in hope that one day I'll crack it! And that you won't get too bored with me!

The ones that got away!

Sometimes you just have to accept that some individuals can't be identified - even if photographed.

I have a few shots of my own which I can't be certain which Featherleg they show.

Featherleg IDs

I, too, have got quite a lot of photos of Featherlegs which I can't ID (hardly surprising!) My question is, can I go on submitting them as Observations thereby learning how better to identify them, or does that break iSpot protocol (too many Observations of the same thing)?

Also, you may find that course a bore.

What can you recommend?

Not sure...

I would say go for it.
I doubt that anyone would complain, especially if they aren't all uploaded together.

The moderators can always add a comment to this, or a later post, if they'd prefer you not to.

Thanks Roy. I will continue. You seem to know more about this subject than anyone else; I should be grateful if you would keep an eye open for these Observations when I submit them (otherwise I shall never learn!).

European odonata.

I think that one of the problems that you have is that you are based, or at least spend a lot of time, in France - at present there don't seem to be many people using Ispot who are confident about the ID of many foreign species!

I'll make a point of specifically browsing your observations (using the search facilities) every now and then - starting with the ones that you have already posted that don't have IDs in the next couple of days.

Previous Observations

Many thanks indeed Roy. This will be of huge help to me.
