don't have a pest identification guide (any www resources appreciated), but
in the meantime, if anyone can identify the pests at:

http://www.lpmd.org/gardens/spirea1.jpg and
http://www.lpmd.org/gardens/spirea2.jpg

i would certainly appreciate it. they don't seem to be stressing the plant
in any way, but i'm just trying to ascertain (1) what they are; and (2)
what, if anything, i should do about them. i'd like to avoid poisions if i
can.

thanks,
