Re: Silver-washed Fritillary life cycle video
A Video critique
My Wife and I really enjoyed this video and I realise the effort that goes into making something like this, with seasonal timing was tremendous.
Very uplifting to watch to try and understand the species needs.
I think we need more locational and dated video clips put together of significant stages of life cycles, to better understand the species.
In England we have a "companionship flight" (previously known as a courtship flight) where a male flies around a female in circles.
I thought we should have a look at that in fast and slow motion and better understand how and why a male might be more successful in mating or an obsessive male rejected by a female.
Also a first flight from pupa was not seen there.
The caterpillar was remarkable in its early stages, with more successful ones seeking shelter and camouflage in rugged bark tree diameters from 60cm or more. That ruled out most immature trees of less than half a metre across, making the species loved in "ancient" woodland. It might take an Oak tree at least 80 years to get to that size.
Where those "special trees" have been identified, by recorded evidence of females ovipositing, habitat manages, in partnership with land owners, might be able to increase a species success rate by making conditions more suitable for violet growth, regrowth and reproduction near to and under canopy of those trees, also with suitable planting and pruning planned. With perennial violets being in leaf full year, protection from trample at specific times, might be of significance.
Protecting and enduring the provenance of violet varieties that had a close evolutionary relationship with Silver-washed Fritillary, with valued propagation, was for future benefit and wellbeing of the species and of those who love this butterfly (that's usually those, like myself, who have loved and seen it in the wild, or have seen videos like this).
I had to hover over the pause button while watching this video, to read all to my partially sighted Wife in time, who also liked it, so an audibly descriptive version, might be of great value to some others and #Sense
Kind Regards
