So far, I've seen aphid clusters by the thousands:
Rose Plume Moth Larvae:
A positive note: whenever there are years of plague like proportions, remember there are natural controls, like this Lady Bug larvae feeding on aphids below. Please look carefully. Beneficial insects are in full force - fighting the good fight. Instead of using chemical sprays, use high pressure water controls, pruning techniques and boosting the health of the plant. Save beneficial insects like Lady Bugs and their larvae, as well as parasitic wasps, lacewings and the birds. We NEED them! Chemicals are not the answer.
We may complain about our harsh winters here in Ontario, but I welcome them. The severe cold kills many overwintering insect adults and eggs. And that, we need!
