are there any pictures of spider mite damage?

Answer 1

Yes, almost all university web sites that have an agricultural program will have pictures of spider mite damage.
I can give a verbal description,
First you will notice that the leaves a drained of color.
Then they start to curl and distort as though they had arthritis, Then you will see webbing on the underside of the leaf first and eventually a closely knit fine webbing everywhere, leaves and flowers will be sucked clean of color and the plant will be webbed all over. If you have a hand lens of 10X or better you can see the MITES along the center rib of each leaf and the eggs at the outside edges . Spider mites usually have 8 legs except for one instar stage when they have 6 legs( pretty sneaky huh?)
Good luck Bugsie
