Periphyllus or maple aphid on vine maple

The most common genera of aphid species found on various maple species are the Periphyllus aphids. We commonly find these species on a range of maples including Japanese maples, vine maple, and Norway maple. P. lyropictus, the Norway maple periphyllus aphid, is found on Norway maples (see images from the Ken Gray collection in the Gallery section) and the California maple aphid, P. californiensis is found on Japanese maples (see gallery images).

Most of these species overwinter in the egg stage. Egg hatch is commonly timed to bud break on the maple host trees. The nymphs and adult aphids are often found on the growing tips of the plants where they feed shortly after hatch in the spring. These aphids can reproduce by parthenogenesis, an asexual form of reproduction. In this case, they give birth to live offspring.

In the late summer and fall, winged (alates) aphids will appear. Mating takes place and female aphids lay eggs, usually near buds, which will overwinter.

Monitor for the eggs near buds and the aphids on new growth and leaf undersides.

For information on management of aphids, check the PNW Insect Management Handbook.
