July moth scarcities, immigration and clearwings

Cedestis gysseleniella Tophill Low NR, East Yorkshire July 2015

The opening weeks of July proved to be a fantastic period for moth recording with several new species added to the Tophill Low NR list in East Yorkshire, including some regional scarcities. All the statistics are taken from Yorkshire Moths.

The highlight of the period was Cedestis gysseleniella taken at light on the 13th July – only two had been seen in the vice-county up to the end of 2014, with only 22 being recorded previously in Yorkshire.

Second in the scarcity stakes, this Hemp-agrimony Plume Adaina microdactyla appeared at light on the 1st. As at the end of 2014, there were nine vice-county records and 27 Yorkshire records. Interestingly, two more were trapped on the 10th, with another appearing on the 13th.

The 13th also saw Crescent Plume Marasmarcha lunaedactyla trapped. Another Yorkshire scarcity, 46 individuals had been recorded in the county by the end of 2013 – 20 of them in VC61.

Other new species so far this month involve Scoparia pyralella on the 3rd, Bryotropha terrella and B. affinis on the 10th, and Crambus pascuella on the 13th – the same date as the first Tophill Lilac Beauty Apeira syringaria.
