A difficult pair

Just had the Mercury Vapour moth trap out for a few hours before bed last night due to the predicted heavy rain and no spare bulb at the moment. 19 moths of 9 species with 5 Setaceous Hebrew Character being the most frequent but also included one of the tortrix moths, Strawberry Tortrix Acleris comariana or Acleris laterana. This species 'pair' are very difficult (or impossible) to tell apart without examination under the microscope, and as I have had confirmed both of these species in the garden trap before it's best to put them down as one or the other.

17 Pink-footed Geese flew over at first light, heading south. I have now had this species flying over the house in autumn each year for the past five so it must be on some sort of flight path for the species. 65 Black-headed Gull, 5 House Martin and a Swallow also flew over heading south this morning. Birds were quite active despite the overcast conditions, with Nuthatch, Bullfinch and Great-spotted Woodpecker all calling from the paddock and 2 pairs of displaying Collared Dove in the same area.
