Shibden Head

I ventured up to the top this morning (sun was shining)!! that's a rarity.
I managed to find 8 Herald Moths in Bare Head Tunnel - but they took some finding. Nothing else of note in there where I found 6 on 11th November with 9 for Andy on 22nd/23rd Nov.
They don't seem to pose very well, and it's not easy getting a decent photo in there ! but they are still very nice to see.

Wall Brown Lasiommata megera Decline

There is an excellent treatise here supplemented with NBN Data showing the decline of this once popular species

Wall Brown Decline

I have noted this species on the peripheral Field Margin adjacent to a dry stone wall well trodden and
near cattle. The annual sightings petered of circa 2011/12 and was also mirrored by a specimen at Ogden LNR on the Easterly side of the reservoir near to the stone walling before going onward up the clough

It begs the question as to where if any there might be  strongholds in Calderdale per chance hanging onto to areas of small suitable micro climate  Some of the reasons for its decline are given below

Wall Brown 4656

Evidence suggests butterfly is dying out because warmer weather is causing generations to hatch out too late in the year to survive There is more here Wall Brown and Climate Impact

micro-climate at the inland sites was on average 1.2C warmer than at coastal sites, suggesting that cooler conditions by the sea enabled the butterfly to maintain its traditional life-cycle.

It begs the question where is it seen in Calderdale and Why and whether numbers could be augmented at this sites by adding bred numbers

This evening in the porch light a new moth for here. I  think it could be a Pale Brindled Beauty (?) but I'm not sure.
Wing length is c 20 mm (wingspan 30+mm) along with a much smaller Winter Moth another of which is in the porch light tonight.

One from Monday night 7th December which looked grey rather than brown ! The pale underwing is throwing me  a bit as is the dark spot on the forewing and wondered if it is getting a bit late for November Moth ?
 I think it's a November Moth agg but not sure ?
Correction - Northern Winter Moth

And one from tonight 8th December - a Mottled Umber

More Winter Moths

Plenty moths in the woods tonight , I counted at least 180 but did not have time to leave the path and get it to main part of the wood. No females or other  species tonight.

On the 9th October I had only one winter moth in the gale force winds...

Beautiful Plume (I think)
