Cone bug: what is its feeding and oviposition behavior?

• A. Sucks conifer seeds while standing on the cone, and lays eggs on foliage.
• B. Bores into cones and destroys seeds.
• C. Feeds on needles only.
• D. Overwins in bark crevices.

Answer: (A)

The cone bug targets the tree’s reproductive structure and uses the cone as its feeding site while it’s there. It punctures the cone scales and sucks out the seeds, directly reducing seed production. After feeding, the female lays eggs on the foliage, which provides protection for the eggs and easy access for the young nymphs as they move to cones to feed. This combination of feeding on seeds inside cones and depositing eggs on leaves is consistent with its life cycle and how it interacts with the tree. It isn’t described as boring into cones, feeding only on needles, or overwintering in bark crevices, which are behaviors of other insects.
