Damselflies are slimmer and more delicate than dragonflies and carry their wings folded vertically over their body. Several species of adult damsel flies occur in cotton, ranging in color from gray to electric blue. Damselflies are too small to tackle a large moth, but if you observe them closely you may see one feeding on aphids or whiteflies. They hover near an infested leaf and periodically dart in to pick off an aphid or whitefly. However, it is doubtful that this predation by damsel flies is sufficient to have much impact on aphid or whitefly populations.
Damselflies also feed on a variety of other small insects.
The variation in crop development throughout the area will make it more important than usual to make insect treatment decisions on a field by field basis. I visited several fields this week that should not need another insecticide application for bollworms or budworms. Other fields have plenty of squares in the top and could easily support another generation of worms. Aphids and whiteflies are building in some fields. These populations need to be watched carefully, particularly as bolls begin to open, to avoid sticky cotton.
