Most crickets lay their eggs in the soil or inside the stems of plants, and to do this, female crickets have a long, needle-like or sabre-like egg-laying organ called an ovipositor. Some ground-dwelling species have dispensed with this, either depositing their eggs in an underground chamber or pushing them into the wall of a burrow. [1]
Crickets are also very efficient in terms of nutrients. For every 100 grams of substance crickets contain 12.9 grams of protein, 121 calories, and 5.5 grams of fat. Beef contains more protein, containing 23.5 grams in 100 grams of substance, but also has roughly triple the calories and four times the amount of fat as crickets do in 100 grams. [31]
The house cricket is typically gray or brownish in color, growing to 16–21 millimetres (0.63–0.83 in) in length. Males and females look similar, but females will have a brown-black, needle-like ovipositor extending from the center rear, approximately the same length as the cerci, the paired appendages towards the rear-most segment of the cricket.
For people needing to boost their iron intake, house crickets and mealworms might be able to help. These insects contain higher levels of iron per 100 grams than beef, pork and chicken, and have a ...
Mole crickets stridulate like other crickets by scraping the rear edge of the left fore wing, which forms a plectrum, against the lower surface of the right fore wing, which has a ratchet-like series of asymmetric teeth; the more acute edges face backwards, as do those of the plectrum. The plectrum can move forward with little resistance, but ...
Mormon crickets also eat insects, including other Mormon crickets, especially individuals that have been killed or injured by automobiles or insecticides. Cannibalistic behavior may be a result of protein and salt deficiency. Swarming behavior may in turn be a strategy to avoid predation by other Mormon crickets. [6]
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
Tree crickets are unique in the way they use carrier frequencies because the range of frequencies changes according to the temperature. Due to this, female tree crickets have tympanum (hearing organs) that can receive a much wider range of frequencies than most other insects. [ 6 ]
