Flavolined Longhorn
A large prionine beetle with yellowish elytra and dark veined patterns, found in the Amazon basin. It is less well known than its more famous congeners. Larvae develop in large fallen trunks in primary forest.
Did You Know?
Adults are attracted to mercury vapor lights and are most commonly collected at light traps during the wet season.
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.
