I'm no expert on the subject, but I've picked up some literature to help me learn more about them. I can pass on a little of what I've learned:<BR/><BR/>As for identification, I think you are correct as to species of mite: Aceria macrorhynchus.<BR/><BR/>The origin of the galls: the female mites spend the winter in crevices in the bark, but emerge to feed on the young leaves as these unfurl. I had assumed that each gall was the result of an egg being laid in the leaf, but that isn't so in this case: here, the galls simply arise where the mites have been feeding, and one mite can therefore cause many galls. Later, the mites lay their eggs in some of the galls, and their developing larvae feed on the tissue inside, emerging in the autumn.<BR/><BR/>I haven't come across any photographs of the mites themselves.<BR/><BR/>I hope this was helpful to you in some small measure. I will take a look at your other pages; it's good to come across someone else who appreciates the micro-life out there. Regards,<BR/><BR/>-DavidAnonymousnoreply@blogger.com
