this is an oak leaf, sorry the picture is not good.
Are you talking about the burnt tip? In my area it would be salt burn, possibly too much water.
it's the under side of the leaf soft insects
Looks like a Ford truck seat. What type of oak? The pattern probably rules out disease pustules, so my guess is a type of gall. Stretching here....best guess is gall caused by mites. Need to know what oak, then research. ???
I'm sayin' Nissan
You're sure they're insects?
Just a Gall (?) spelling,. Could be a parasitic wasp unsightly but generally does no damage to the tree. Nothing you can spray or do far as I know.
Gall wasps (Cynipidae), also called Gallflies, are a family of the order Hymenoptera and are classified with the Apocrita suborder of wasps in the superfamily Cynipoidea. About 1300 species of this generally very small creature (1-8 millimeters) are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.
