Black vs Brown Crickets: Difference and Comparison

Black and brown crickets, variations of the common cricket of the family Gryllidae (which belongs to the subfamily Gryllinae and the order Orthoptera), are insects closely connected to bush crickets or katydids and remotely related to grasshoppers.

Key Takeaways

1. Black crickets (Gryllus Bimaculatus) and brown crickets (Acheta Domesticus) are two common species used as live food for reptiles, amphibians, and birds.
2. Black crickets are larger, noisier, and more aggressive than brown ones, which tend to be smaller, quieter, and less aggressive.
3. The choice between black and brown crickets as a food source for pets depends on the size and preferences of the animal, as well as factors such as noise tolerance and ease of handling for the owner.

Black vs Brown Crickets

The difference between black and brown crickets is that black crickets are significant, more aggressive, and brawnier with a hard exoskeleton, making it hard for insectivores to bite and mostly remain on the ground and move more slowly than the brown ones. In contrast, brown crickets are slimmer, less aggressive, more compact, have a softer exoskeleton which makes them easy to chew and has large muscular hind legs, which help them jump about more frequently than black crickets.

Black crickets are primarily classified as field crickets because they are mostly seen outdoors, while brown crickets are categorised as house crickets because they are found in residential areas.

Crickets are categorized as omnivores and are considered scavengers for crickets feast on dying or dead life forms (like plants or insects) in the environment and are likewise favoured as a food source for a variety of reptiles like lizards, spiders, and frogs.

Their anatomy consists of a hard exoskeleton, segmented narrow body, two compound eyes and three simple eyes, well-built hind legs for jumping, two long antennae, straight leathery forewings which serve as an outer protective cover for the large and delicate rear wings, strong jaws for biting, two cerci and an ovipositor (only in females).

The male crickets are prominent for their chirping sounds, produced by rubbing their forewings together.

The black crickets are mostly found outside and are said to be field crickets.

The black crickets are large, meatier, and have spindlier legs. Although the black crickets move pretty slowly, they are considered very aggressive and most likely ought to bite.

Black crickets are considered omnivores and are said to feed on plants and animal mostly remains. Black crickets are primarily found in the United States, Australia, Mexico and Canada.  

A female black cricket can lay up to 400 eggs, and its general life expectancy is expected to last only a few months.

 

What are Brown Crickets?

Brown crickets, also known as the Acheta domesticus (scientific name), belong to the same family of Gryllidae. Brown crickets are said to be house crickets and are found inside residential areas.

Black crickets are primarily found in Southwestern Asia. In the years 1950 and 2000, brown crickets were mainly used as food in research centres, but now, brown crickets can also be ideal pets.

Brown crickets are, as the name suggests, brown and are 16-21mm in length. Brown crickets are said to have a softer shell, slimmer, and jump more when compared to black crickets.

Brown crickets do not have an aggressive temperament and are most suitable for feeding other domestic animals like iguanas, frogs, lizards, etc. Brown crickets are quieter. They are not as noisy as black crickets.

In 2002, the breeding of house crickets in cricket breeding industries initially stopped due to the cricket paralysis virus but then later continued again in 2010. The house cricket is also an edible insect.

In south-east Asia, America, and Europe, people consume brown crickets, for they are said to be a protein dish that contains omega-3 and omega-6 fatty acids.
