Nettle-tap Flea Beetle
A tiny yellowish-brown flea beetle found on watercress and other crucifers in damp habitats. Larvae mine in plant roots. Can be a minor pest of commercial watercress.
Did You Know?
Commercially grown watercress can be damaged by this beetle, which is nearly invisible to the naked eye.
Common Water Strider
A slender dark brown insect that skates across the surface of streams and ponds using water surface tension. Its long middle and hind legs distribute its weight over the water film.
Did You Know?
Tiny hydrophobic hairs on its legs trap air and repel water, allowing it to stand on the surface without breaking through.
