Well, to add to my theory this spring has generally been cold, with average temperatures in April being lower than in December. It actually snowed here yesterday. Judy and Terry Wood reported the first Large Red Damselfly emerging from their garden pond in Polebrook on 27 April which closely matches their previous first emergence dates from this pond. This weekend looks warmer with more sunshine so I'll be out and about hunting for more.
