Early Season Aphids

Many early season aphids can cause extensive leaf curling and cupping on new growth. I have included pictures of aphids on euonymus and flower thistle- but you can find similar injury on ash trees, viburnum , birches and other plants- It is a cosmetic damage and many times by the time you see it the populations are on the down swing. The warm weather promotes many of the insects that eat aphids – so the good guys should be catching up.
