  • Masked hunter

    These black or dark brown bugs measure from 16 to 22 mm long. They have an elongated, oval shape and a small head with sharp mouthparts. They use this beak-like “rostrum” to spear their prey so that they can feed on it.

  • Meal moth

    These moths are recognizable by the two curved white lines on their forewings. The middle part of the wing is a lighter brown than either end. The wingspan is 15 to 30 mm. At rest, the moths adopt an odd posture, holding their wings flat and curving the abdomen upward.

  • Oblong-winged katydid

    These green crickets are 40 to 52 mm long. When populations are dense, it may be possible to find some yellow or bright pink individuals. As in other members of the Tettigoniidae, their antennae are longer than their bodies. The oblong, fairly wide wings also extend past the abdomen.
