February's not a great month for moths

Well so much for the jungle of Steeple Morden being swarming with moths. All I have managed to get so far is one Chestnut (yesterday) and a few Tortrix. How is Will managing to get so many? Is Potton a moth Mecca? Is my moth trap a dud? Are the plague of birds in my garden somehow getting into the trap and back out again? Well, they would have to be pretty cunning.
