Exapion Ulicis (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Exapion ulicis (formerly Apion ulicis) is a species of straight-snouted weevil known by the general common name Gorse Seed Weevil. It is used as an agent of biological pest control against the noxious weed known as common gorse (Ulex europaeus). The adult weevil is light gray in color with a long snout half as long as its body. It is 2 to 3 millimeters long in total. The adult feeds on gorse by digging into the soft tissue of the stem and spines with its snout, creating characteristic round holes as evidence. The larva does more damage, however. It emerges from its egg inside the gorse seed pod and feeds on the seeds for six to eight weeks. The larva then pupates for about two months.
