Here's my critique - something to chew on
Antonym
Definitely different - and definitely behaviour! A nice sharp shot - although the burnt-out white in the bottom right-hand corner really spoils it for me - looks like you were using flash. I would have made it portrait and cropped that corner out (I just tried it and it looks MUCH better!).
Charles Nicol
Interesting shot that would be better-placed in "up close and personal". Good closeup of the wing but the butterfly is too cropped for my liking, and the red and white cloth also detracts in my opinion.
Dave McCormick
A very unusual shot indeed and nice colours. The composition is quite good too - although a shame that the wings are at such an angle and partially-obscured.
Deano
There's something surreal about this shot, which I like a lot. It almost looks like a watercolour. And, I have to admit, was the inspiration for me entering my Brimstone shot! The only comment is that I would have cropped some of the space on the left of the frame.
Denise
One of my favourite shots and you've achieved a good balance of sharpness and grain. Great colours on the butterfly too. The only minor annoyance is that frond coming into view on the right.
FISHiEE
As ever, another superbly-executed shot. Nothing else to say really!
Gruditch
Another of my favourites and up to the usual standard. Great composition and I didn't realise that grass could look so beautiful!
Gwenhwyfar
Fantastic shot Lisa. I can see why Gruditch manages to take such consistently good shots when he has you to show him how it's done
Ian Pratt
I quite like this. And getting both upperside and underside in one shot is pretty good going! Also a nice out-of-focus background and colour contrast.
Keith Woonton
I like this shot - definitely representative of what Brimstones do best! As for others, I think this would have looked slightly better had the butterfly not been dead-centre.
Markulous
One of the most interesting shots of the lot - and definitely behaviour! The wasp and caterpillar are both on the soft side for my liking but an great attempt nonetheless.
NickB
Yum yum. A classic Emperor shot - nice one! Looks like the light is on the wrong side of the butterfly - so you've done well to compensate for that. I'm undecided if I like photos in a square frame
Paul
Two nice fresh individuals and a really sharp photo! I think the shadows are slightly distracting.
Paul Brock
A nice shot and you've done well to get the blue irridescence on the wings. The photo is a little soft and I would also have placed the butterfly off-centre in the frame.
Polly
A nice camouflage shot. As for others, I think the shot would have looked better if the butterfly wasn't in the middle of the frame.
Shirley Roulston
A lovely sharp shot - well done! And a great example of the difference between male and female undersides. I think the butterflies would have looked better if they were more off-centre, and the whites on the twigs look a little burnt-out.
Susie
Lots of good elements here - and I especially like the colours that the flowers add. What put me off though is that this critter looks crippled to me - since butterflies pump up and dry their wings with them held vertically down.
Sussex Kipper
I've never seen a Purple Emperor at a sap run, so thanks for sharing that Neil! Very unusual and definitely behaviour. The only negative is that the butterfly is at an awkward angle, so you don't get the full benefit of the superb underside colours.
Sylvia Godfrey
Nice head-on shot of a Small Skipper, and you've done well to get the proboscis in focus. The fly is a bit annoying but the composition is very good with a nice balance of the butterfly and the flowerhead.
birdy43
Nearly a great shot! Unfortunately, I think there's a little too much blur (and grain) - but a great effort anyhow. Keep it up!
eccles
I really like this shot. Great colours, great composition. Keep it up!
geniculata
Very nice colours, and the difference between male and female stands out very nicely. The critters are rather central in the photo, but I'm not sure what I would have done about that - possibly tried something in portrait mode.
jackharr
Really nice colourful shot and super-sharp. It's a shame that both butterflies are facing away from the camera - with both heads being partially-obscured. I also didn't think there was much behaviour either - but that's just my view. Definitely one of the best shots you've entered.
johnb
Interesting shot - and definitely behaviour! It's a little on the soft side for my liking and the grass blade is just annoying! But well done for capturing such a rare sight.

My personal opinion is that multi-photo images don't represent "a" photo in "a" photo competition. So - not sure which one to comment on

Interesting photos nonetheless!

See above.

A beautiful picture with a superb colour contrast. On the same plant as your Speckled Wood a couple of competitions ago! The only niggles are the nick on the apex of the left forewing. Also not too much behahiour in my book. Otherwise superb.
wavelea1
Hmmm. Not much behaviour there - but well done for trying something different. The light seems to be behind the butterfly which makes the subject look overly-dark.
web4160
Nice behaviour shot - people tell me about this behaviour but I've never seen it myself. Portrait mode may have worked better so that the critters aren't dead centre in the frame.
xmilehigh
Great shot - I really like it, although it's a shame that the bee in flight is blurred. Also - the leaf coming into the photo from the top is a little off-putting, but a jolly good shot nonetheless.
Cheers,
