2018 January Moth Challenge

Hello Mothers,

The January challenge has now finished, the data is all in and has been collated in the two charts below.

This year 12 mothers took part (one more than last year) and between us we recorded 22 species, the same as last year (11 macro and 11 micro) and 204 moths (179 macro and 25 micro), which is again an excellent effort on everyone's part. However, in general, moth numbers were well down on last year.
Only one person achieved the macro part of the challenge, with 10 plus species that was myself with 10 species. Julie Pearce/Mark Thomas and Sue Southam were next with 6 species. I also managed to achieve the micro part of the challenge with 8 species.
The six recorders who managed to record nothing this year will have to share the coveted ‘wooden bulb’ award (formally the ‘wooden spoon’ award).

Now for a more in depth breakdown of what was recorded.

Macros - As can be seen in the chart below several people managed to record 3 species. Across all recorders the most numerous species was the Winter Moth with. Once again the Mottled Umber came second with 31 moths and the Mottled Grey was third with 26 moths.The most moths recorded by individual recorders was 125 by myself, Sue 32 and Julie/Mark 21.Of the 11 species recorded, none were totally unexpected, although the Pale Pinion and Spruce Carpet are always good January records.

Micros - Interestingly, for the first time, the micro species recorded of 11 matched the macro species recorded, so that was a particularly good effort on the part of the five recorders trapping something (one up on last year). The species recorded by the most recorders was once again Agonopterix heracliana (2 people). No unexpected micro species were recorded this year.

The evolution of butterflies and moths

Many of you probably saw the recent discovery of ancient moth scales in the news. Following on from this discovery, I wrote a blog on the early evolution of Lepidoptera - including what the first moths living over 200 million years ago looked like and some of the reasons why the group has since evolved to be so successful. Might be of interest in these winter months when the trap is (relatively) quiet?
