What is an aphid?


Aphids are small (less than 1/4 inch long), soft-bodied insects that suck sap from leaves, twigs, or roots. Depending on the species and the plants they feed on, they may appear:

  • Black
  • Brown
  • Green
  • Red
  • Yellow

They are pear-shaped insects with long legs and antennae. Adult aphids can be winged or wingless. They are often clustered on new growth.

Habits & Reproduction

Although aphids are most common in spring and summer, some species mate and produce eggs in fall or winter, which provides them a more hardy stage to survive harsh weather. Under ideal temperatures, many aphid species can complete their life cycle in less than 2 weeks, and because of their prolific reproductive capacity, enormous populations of aphids can build up in a short time.
