Norfolk moths: Rockland St. Peter garden, 9 April 2014

After a cool, but cloudless and sunny day, there was a think layer of high cloud overnight, which covered a half moon. The temperature was 12.1°C at 22h45, falling to 7.5°C by 05h50 when I turned off the trap, although it felt cooler. There was a barely noticeable movement of air.

A Blackcap sang, moving in an arc around me and finally showing itself in our tall birch tree, as I unloaded the trap in the half-light.

A good night, with eight species new for the trap. Oaks are the larval foodplant of the Frosted Green and it is usually found in woodland, so is presumably not a common species around here. Scorched Carpet larvae feed on Spindle Euonymus europaeus, a plant that occurs at low frequency in hedges and which I have planted in the garden; the moth's UK range mirrors that of the foodplant, which is largely restricted to southern England. The Streamer is a striking and distinctive carpet, while Brindled Pug – another species whose larvae feed on Oak – is a bit more subtle and something of an identification challenge (expert Great Ellingham mothman Chris Knott confirmed this one). The smaller Double-striped Pug is easier to identify and shows that pugs are worth a second look: this one really was rufous-banded (rufifasciata). And at last: an Oak Nycteoline. A single male Brindled Beauty and a couple of male Muslin Moths were the pick of the trap.
