11 of these across 2 traps in Coed Y Bont last night! 8w and 15w actinics. Apologies for quality of pic but it shows the hindwings well.
2 Mottled Umber
11 December moths
1 Red Swordgrass
The experimental LED trap was set up at home but had to be put away quick when we had some unexpected rain.
Seeing Sarah's earlier report of December Moths, I thought it would be interesting to look at the county records for this species. Below is the graph of number of records per year from 1966 to 2015:
The graph clearly shows the introduction of Ian's RIS trap in 1976, at which the numbers have declined a little in the past 40 years. It also shows the increased interest in year-round moth recording when the moth group was formed in 2009. Prior to that we had numbers of lepidopterists visiting Ceredigion, but mostly in the warmer months and hence few records for December moth.
Nothing of note here lately. Last night's garden trap resulted in 2 December Moths (my first of the winter) and a Feathered Thorn. I also trapped on Sunday night and had a Winter Moth, 2 Feathered Thorns and a November Moth agg. (and a wasp).
Third edition Field Guide to the Moths of Great Britain and Ireland Field Guide to the Moths of Great Britain and Ireland has been fully revised and restructured, to reflect the latest thinking in taxonomy. There are new descriptions and illustrations for newly discovered species, and existing entries have been updated, with distribution information revised and maps included for the first time.
Can someone tell me what is going on here please? These two were in the trap this morning. Both have broad, feathered antennae, so I take them to be males. Is such a large variation in size usual with this species?
