The Jamaican Field Cricket15/04/2021
Gryllus assimilis, commonly known as the Jamaican Field Cricket and sometimes referred to as the Silent Cricket among other names, is one of many cricket species known as a Field Cricket. Its natural habitats are the West Indies and parts of the southern United States, Mexico, and South America, though as a result of widespread breeding programs to supply feeder insects to the pet industry since 2010, it has become available commercially throughout North America and Europe.
Females deposit as many as 400 eggs via an ovipositor into damp soil. At suitably warm temperatures (between 25 °C (77 °F) and 30 °C (86 °F), eggs usually hatch in about eleven days. Nymphal stages take place for another three six to seven weeks, at which point the insect reaches sexual maturity and the males begin calling for females. Eggs are often consumed cannibalistically by adults searching the soil for food.
They are a very popular food for various lizards including Bearded Dragons, Leopard Geckos, Frogs and Water Dragons. By choosing to feed your reptile livefoods such as these crickets you will be promoting a natural hunting, stalking and waiting behaviour from your reptile which keeps them active and occupied and is more what they would be accustomed to in the wild.
The Jamaican Field Crickets are readily taken by a host of reptiles, amphibians and inverts and make a meaty and nutritious meal when gut-loaded with the right diet. Gut-loading is the practice of feeding crickets and other feeder insects with highly nutritious food items that will in turn make the feeder insects more beneficial to the health of your exotic pet. Crickets are also suitable for dusting with vitamins and calcium prior to being fed to your pets.
The various life stages of Gryllus assimilis will offer a wide variety of prey sizes to offer your exotic pet, with newly hatched pin-head crickets being suitable for smaller exotic pets and fully-grown adults being suitable for larger specimens.
The Jamaican Field Crickets are easy to keep and cheap to feed which makes them a good, affordable choice to have as a handy food item. The only downside to keeping crickets is their relatively short lifespan, so care must be taken to ensure you have a constant supply available through breeding within the colony.
