F/potty they only hatch out of their pupae in spring mate then lay their eggs, here's a link to the life cycle.

Winter mothOperophtera brumata has wingless females that do as you describe.

Discovery apples are self sterile. If the nursery it came fromlabelled it as self fertile, you could take it back. But even self-fertile apples crop better with a pollinator around the place. If you have gardens near you with apples trees or crab apple trees, the likelihood is there will be a pollinator within bee range anyway.

 

Can't take it back - 250 miles away from me !! I don't live in my home county of Norfolk now .. been all round the estate and that is the only fruit tree ! Not too far from me so here's hoping, and I do have lots of plants in my garden which attract the bees .... I would go buy another, but the trees in the garden centres around here are a ridiculous price .... Val
