Yes. But compare to pigs or cattle, insects in general produce much less greenhouse gas, in the form of methane-tainted farts. The flatulence of all other insects, like the crickets and mealworms, is methane-free.
Cricket 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
Crickets are omnivores and scavengers feeding on organic materials, as well as decaying plant material, fungi, and seedling plants. They live under rocks and logs in meadows, pastures and along roadsides. Many are nocturnal.
Cricket's 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.
