Is there a coincidence that weevil has evil in it? MICRO Team member Lyndon Colvin was working in the lab thinking about lunch when an unwelcome visitor found his own lunch; Lyndon’s leg. After being mistaken for a pecan and having his leg drilled into by the visiting weevil, Lyndon was gracious enough to capture him using the swat and shake method. Although the swat and shake method is not very useful for keeping something intact (and the weevil lost one of his legs), Breanna Jones, our work-study student, was still able to use it to complete her first scan. After some research we determined that it was a pecan weevil.
These weevils are known for their long snouts that allow them to bore into pecans or other nuts. The weevil goes through four life cycles within two to three years. These cycles are: egg and larva inside a nut; pupa living underground; and adult which emerges from the soil. They are most active from July and into October, which is exactly when ours was found. We believe this weevil was a male due to the phenotype of the snout. Male snouts are characterised by being about three-fourths the length of the body. She chose to showcase the distinctive snout as well as the mesmerizing symmetry of the wing pattern in this video.
