Hackberry Nipple Galls

Hackberry nipple galls were peppered all over the leaves on a hackberry tree that grew along the path at an arboretum.
 Hackberry nipple galls are caused by hackberry nipple gall psyllid (Pachypsylla celtidismamma).  Their galls grow on the undersides of hackberry leaves

The gall makers are also known as jumping plant lice and they look very similar to the hackberry petiole gall psyllids that I posted about earlier.
There are many flowers and plants to photograph at an arboretum.  About all I took pictures of was that hairy thing.  What's up with that?
