Moths: March 17
Despite the only moth of the night before, a Clouded Drab, not even making it into the inside of the trap and that the cold Easterly continues to blast there were more moths. A bit of cloud kept the temperature at 7.7°C and there 11 moths in the exposed trap. These included the first Pale Pinion and Bright-line Brown-eye of the year. In the sheltered Whitehouse there were 39 moyhs including a Twin-spot Quaker.
The cold wind continues and the temperature dropped to 2.6°C but it remains extremely dry. It will be interesting to see if this has an effect on the moths as well. Only ten moths in the main trap but a run out for a new portable trap in the Whitehouse showed moths were still around in sheltered spots. 27 moths included the first Powdered Quaker of the year.
Despite the strong cold wind continuing there were 38 moths in the trap including the first teo Early Thorns of the year.
The return of strong wind did not reduce the night time minimum below 10°C but drastically reduced moths to 23, this included 2 more Red Chestnuts.
An excellent haul, for us in March, of 85 moths was bulked up by Hebrew Characters and Common Quakers. It did include another Lead-coloured Drab, three Red Chestnuts and a Diurnea fagella. The second migrant Diamond-back of the spring reflected last weeks mild spell.
A decent night again that produced Oak Beauty, which we failed to record last year, and only the Bay’s third record of Lead-coloured Drab.
An excellent total of 63 moths included Twin-spotted Quaker, Double-striped Pug and Red Chestnut for the first time this year.
Even cooler, down to 1.6°C, but still 28 moths. Two March Moths, an Engrailed and an Early Grey were new for the year.
Slightly cooler, down to 5°C, and a bright moon at times but this did not deter the moths there were still 24. Clouded Drab, Chestnut and Acleris schalleriana were new for the year. The latter is only about the third adult record but its larvae have been found.
The mild spell is finally having an effect and there were 28 moths in the trap. All four species were new for the year; Hebrew Character 20, Common Quaker six, Small Quaker one and one Epiphyas postvitana.
The forecasts are generally not good enough to risk the trap surviving in such an open spot, but they have been wrong overnight at least twice. A Pale Brindled Beauty was attracted to the car park floodlight tonight.
