Cherry
fruitworm moths typically emerge a little earlier than cranberry
fruitworm, and egg laying begins immediately after petal fall.
Eggs are round, flat, and shiny and are laid in the calyx.
Larvae often enter berries in the calyx or on the berry side.
The larva resembles
cranberry fruitworm but has a dark head capsule and a reddish
body, reaching 9 mm in length. Because they develop inside a single
berry, cherry fruitworms cause little webbing, and infested fruit
often drop off before harvest.
