3_redadult.jpg (37501 bytes)Later red stage of adult boll weevil. 4_PastredBW.jpg (44773 bytes)Adult past red stage, but legs, antennae, and snout still lack brown or dark color.
5_Notmature_BW.jpg (43714 bytes)Not mature adult with lower leg parts and antennae still light or reddish color. 6_matureBW.jpg (36558 bytes)Close to mature adult boll weevil, but still light colored parts on extremities.
7_matureadult.jpg (33044 bytes)Mature adult with most - to - all body parts dark colored. 8_near mature.jpg (32132 bytes)Close up of not mature adult leg with dark femur and double toothed spur and light or reddish tibia.
9_maturescales.jpg (59573 bytes)Close of wing cover with scales and red brown color, this would appear gray to just dark in more distant view. Shape of scales are one of the key identification characters for boll weevils. These images were taken from a microscope, hence the odd coloration.
