Could be three things:
Migrant
Captive
Other
Apparently you can go years without seeing one and suddenly, there they are from what I was reading.

Look at the photos on the Hants IOW site. No doubt whatsoever.
I suspect it arrived with last week's "Spanish Plume". This is a weather phenomenon where hot humid air, potentially wet and thundery, moves up from Spain and western France. Now of course, there was a major event lat the end of ast week that resulted in the floods. It has long been believed that birds can be inadvertently "sucked up" in to such developing weather systems (very strong up currents) and there is every reason to presume that the same happens with butterflies.

If they are there now, would they stay? This could be an importance. They were here once, would they breed and establish again?

Birdguides reporting 2 BVW present, one of which was killed by a wasp. I suppose this means the chances are heavily in favour of them having emerged or been released locally rather than being vagrants themselves !
I'm not up on their life cycle. Would it be possible for a pregnant vagrant to give rise to these individuals, having mated over on mainland Europe, or would vagrants have to meet and mate in the UK for these individuals to have a chance of not being releases ?

Stockbridge Down is only 4 miles from our house. But we never bothered to take a look till we were passing today. Judging by the flattened foliage, it sure has attracted some attention. I quized some of the people there and some had driven an hour or two to get there. And about one in three people were self confessed bird twitchers who were coming to have a look at a rare butterfly.

Depends if you think this is a genuine migrant or a release. Seeing 2 in the same place, but nowehere else in the country, would favour the latter! Apparently, one was seen egg-laying today.jackharr wrote:I wonder if this is the biggest butterfly twitch ever?

I think it's on a par with the release of Large Copper last year.

I guess we are unlikely ever to know unless someone owns up.
But I still think the storm assisted arrival (my earlier post) is definitely plausible.
More than one wouldn't prove anything one way or the other. If indeed storm assisted then it would be quite possible for several to arrive in the same general area.
So egg laying? And at least two?
