Cotton Square Borer

This is an adult cotton square borer, also called a gray hairstreak butterfly. The larvae only rarely reach concerning numbers in cotton. This one is laying eggs on pre-bloom sorghum head. They are not considered economic pests in sorghum, but can be found occasionally while sampling for headworm. The larvae are short, light green and look velvety, very easy to distinguish from a corn earworm or fall armyworm.
