A wonderful 15 minute video showing the life cycle of this species. Filmed entirely in the wild in France by VarWild.

Thanks go to Roger Gibbons for drawing it to our attention.

I’ve watched it and thoroughly enjoyed it.
What patience these naturalists have.
Well done.

A super video. Some of the long zooms, might have had, just a little more image stabilisation.

Q1. If Sir Winston Churchill was left in charge of the Black-veined White's comeback in the UK, was that a political mistake? Not everyone might of had reverence, for bringing back extinct butterflies, rebuilding England after WWII.

Q2. A Black-veined White appeared to have spent most of it's life cycle as a larvaI. In climate changed England, might larvae have not gone into a proper diapause, so being more vulnerable to predatory birds, that might have noticed it, before Hawthorn leafed?

Q.3 If it needed "caterpillar conservation" to help it with it's life cycles in Scotland, might that be a less harsh predatory bird winter in England?

To better understand how a Black-veined white butterfly might have camouflaged roosting and/or ovipositing, one might have looked further at it's global, native (less controversial) distribution & what other larval food plants, it might have evolved to use.
