Re: Red Admiral overwintering 2017-2018

This research suggests that Red Admirals, probably in all stages, are capable of surviving UK winters, at least in the less cold places. But the problem seems to be the shrivelling up of the main larval food plant, Nettle. I have to wonder if other known food plants, eg Mallow, are better able to wi...

Re: A Beginner - Identification

I must be overlooking something here. I can't see where Ian Beever lives as that could be highly relevant as to when to release the butterfly into the wild. Early March (on a fine day of course) might not be too early for an extreme southern coastal locality in Britain.

Re: Neil Hulme

I notice that one of the photos shows the clearing In Clapham to be quite close to the edge of wood with arable land just beyond.
Presumably PBF habitat doesn’t need to be deep in woodland?

Re: Red Admiral overwintering 2017-2018

Researchers. I hope you realise that Moses Harris, Frohawk, South, Ford et al will now be turning in their graves at the way you have challenged the received wisdom. However, maybe the Red Admiral has evolved and nowadays has adapted to be able to overwinter at various stages of its life cycle. If t...

Re: Jack Harrison

Old Butterfly Books I have just bought (from a local second hand bookshop) an original of E.B.Ford’s classic ‘Butterflies’ for a mere £5. Condition is good rather than perfect – certainly better than my own very-well loved copy given by favourite uncle way back in 1946. The inscription in these old...

Re: Neil Hulme

With all this clearance to make PB Frit habitat, one day it might be simpler to produce maps showing where PB Frits DON’T occur :P

Well done Neil.

BTW. Do you address Viscount Cowdray (Michael Pearson) as Mick or Mike?

David M. I just hope this week's forecast storms don't do any damage. If the October1987 storm can be viewed as a precedent when it cleared a lot of woodland, Neil's team might regret the wasted effort if nature does it for them :( The worse damage from any storms might be the misguided contractors...

I find this all quite extraordinary especially after the recent cold snap. Excellent research.

DavidM ...given that this [RA] is not a naturally occurring year round UK species...
But isn't this the point? Recent research (as revealed on ukb) shows that RA does indeed over-winter in UK but in an immature stage, not as an adult as many might have thought.

Re: Red Admiral overwintering 2017-2018

I am NOT an expert. But my ten penn'orth: , violet leaves are small, perhaps 1.5 cms across. Mallow leaves are substantially bigger at 5+ cms. Here on the (almost) frost-free coasts, eg Findhorn, Mallow grows into sizeable bushes some as tall as 1 metre. Regardless of what species you have found the...

Re: Red Admiral overwintering 2017-2018

Surely that can't be Mallow. See viewtopic.php?f=8&t=9581&start=20#p127040
If it is, it would neatly square the circle.

Re: Red Admiral overwintering 2017-2018

MALLOW. In Malta, and no doubt other places, Red Admirals seem to prefer mallow as the larval foodplant (I'm not sure nettle grows very well there in such a dry summer climate). I have artificially fed Red Admirals here on mallow. Now mallow surives winters quite well (as opposed to nettle which shr...

Re: Neil Hulme

I'd missed that other pit. There seems to be an even smaller one just to the southwest.

At least this proves that I do look at your writings/work.

See you early May I hope.

If I have correctly identified the pit from OS and Google Earth, it would seem that the northern section of the pit is littered with [presumably] abandoned buildings and/or vehicles. How do you deal with these? Or don't you? And once the pit is opened up, how do you prevent it becoming a playground ...

Re: Red Admiral overwintering 2017-2018

This is excellent research and clearly shows that the conventional wisdom is wrong, namely that Red Admirals, if they do manage to hibernate, only do so as adults.
