Identifying Features
Appearance (Morphology)
- Brown to black
- Front wing varying in length, covering half to
entire abdomen
- Antennae about as long as distance from head to
end of abdomen
- Wings held flat over body
- Hind wings folded and hidden under leathery front
wings
Adult Males and Females
Female with long ovipositor (ventrally attached) in rear
(may appear as two pieces); both sexes have cerci
(segmented, tail-like appendages attached dorsally). The
wings are fully extended over the abdomen. Some species
may not have wings.
Immatures (different stages)
Immatures look like adults, but do not have fully
developed wings. Older nymphs may show development of
wing pads. The female's ovipositor begins to show before
it is an adult and increases in length with each
successive molt.
Natural History
Food
Crickets are omnivores and scavengers feeding on organic
materials, as well as decaying plant material, fungi,
and seedling plants.
Habitat
Crickets live under rocks and logs in meadows, pastures
and along roadsides. Many are nocturnal.
Predators
Spiders, some wasps, ground beetles, birds, small
rodents and lizards are cricket predators.
Interesting Behaviors
To attract mates, males produce a sound made by rubbing
their forewings against each other. The resulting
chirping sound is picked up by the female's ears on her
front legs. The chirp sounds are different for each
species so that individuals can find their own species.
Females lay eggs in the soil with their ovipositor.
Impact on the Ecosystem
Positive
Crickets breakdown plant material, renewing soil
minerals. They are also an important source of food for
other animals.
Negative
Crickets may injure seedlings and large numbers can be
destructive. Males songs can be quite loud.
