Pecan weevils: Identifying the sexes
Female adults are usually larger than their male counterparts. Females also feature an much longer snout, often stretching longer than the length of her body. Female weevils use their proboscis to puncture the shuck and shell of pecan and hickory nuts. Once they puncture the nut, they insert their ovipositor in the hole and lay 5 to 7 eggs within the nut's shell.
