Toadflax Seed Weevil
A small dark weevil that develops inside the seed capsules of toadflax and snapdragon plants. Larvae consume developing seeds. Part of the biological control program for invasive toadflax.
Did You Know?
Larvae can destroy up to 90% of seeds in a toadflax capsule, significantly reducing plant reproduction.
Rustic Longhorn
A grey-brown cerambycid with wavy pale transverse bands on the elytra, found across Eurasia in birch and poplar forests. It is a common borer of weakened and recently felled broadleaf trees. Adults are diurnal and fast-running.
