Long-winged Conehead
A slim green bush-cricket with a pointed head that has dramatically expanded its range northward in Britain. Produces a very high-pitched, barely audible song. Found in tall grass and rushes.
Did You Know?
Its ultrasonic song is at such a high frequency that many people cannot hear it, even when the insect is nearby.
Rice Water Weevil
A small, grey-brown weevil that feeds on rice roots as a larva and on rice leaves as an adult. Adults create distinctive narrow feeding scars along the surface of rice leaves parallel to the leaf veins.
Did You Know?
Larvae feed underwater on rice roots, surviving by obtaining oxygen from the rice plant's aerenchyma tissue through specialized spiracles.
