I think this is a shuttle shaped dart from consulting Waring, Townsend and Lewington it is exactly the right size and very similar in pattern characteristics. But I would welcome comment.
By the way I am getting very few moths in my Skinner Trap. Double striped pug/Herald/clouded Drab/Common Quaker/Hebrew Character so far, all in very small numbers. Trapped 3 times since 24th April. Is this surprising?
