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.
Margined Leatherwing
An early-summer soldier beetle found across eastern North America with yellow elytra edged in dark margins. It visits a wide variety of flowers.
Did You Know?
Unlike the similar goldenrod soldier beetle, this species appears in late spring rather than autumn.
