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]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
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).
Ovuliparity means the female lays unfertilised eggs (ova), which must then be externally fertilised. [10] Examples of ovuliparous fish include salmon, goldfish, cichlids, tuna and eels. In the majority of these species, fertilisation takes place outside the mother's body, with the male and female fish shedding their gametes into the surrounding ...
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.
Both male and female sagebrush crickets are flightless. [1] They have a large pronotum that covers the base of the fore wings. Though they are similar in morphology than C. buckelli , another grig species, they can be distinguished from the other based on the male terminalia and are distinguished from C. monstrosa by having a cream white venter ...
Gryllus bimaculatus is a species of cricket in the subfamily Gryllinae.Most commonly known as the two-spotted cricket, [2] it has also been called the "African" or "Mediterranean field cricket", although its recorded distribution also includes much of Asia, including China and Indochina through to Borneo.

It is thought that spawning occurs inshore and a mature female may have an estimated fecundity of >1,000 eggs. The eggs are planktonic. [1] The silver cyprinid breeds throughout the year with two peaks, the first in August and the second in December-January. It is fast growing and reaches sexual maturity at ages which vary from 16 to 25 months. [5]
