The warm weather is encouraging moths to disperse locally. I caught the first Double Line for my garden in Taunton on Thursday night. This species is found locally in the unimproved grasslands, heath and wood edges of west Somerset. It also tends to wander, as Michael Barry caught it nearby when he lived at Hillfarrance. On Friday night I recorded Grey Arches for the first time at home. This is more widespread north of Taunton and I had seen it previously at Hestercombe, so not very surprising.

I saw quite a few Small Argent and Sable this week around Pinkworthy on Exmoor. This moth is day-flying and occurs across a large area of the moor, though it is still considerably underrecorded. Look for it in the afternoon, particularly after 3pm when there is a strong flight. It would also be good to find it on the Quantocks - the heath west of Dead Woman's Ditch looks suitable.
