New-bee here, a little stumped. I have bees, about 10 or so, crawling on lawn near hive. They all have one normal wing and one that is damaged, not curled or a stump, normal length, just no webbing(?). It's as if there is a bone structure or frame, just missing the rest of the wing. Mite count of 8 or less per 24 hour (natural drop). This is nit described in dwv threads I've searched. Older foragers who got worn out? Or something more serious requiring treatment? Thanks in advance.
