Seed and Cone Insects of Southern Pines


Flower and Conelet Damage

This category includes insects that feed primarily on the male and female flowers and developing conelets of pines. Insects that feed on flowers or conelets but which also commonly damage cones and seeds are discussed in other sections. These insects are, however, included in the key to flower and conelet damage.

Flower and conelet losses often are overlooked because the flowers and conelets are small and the insects feeding upon them may be minute or inconspicuous.
