Black cherry aphids

I let these black cherry aphids get a bit out of hand, but treated recently with Movento (Bayer). That should do an effective job of getting rid of them. Left uncontrolled, they will seriously contort and stunt growth of developing leaves/foliage. For more on black cherry aphid, see: http://jenny.tfrec.wsu.edu/opm/displaySpecies.php?pn=420
