Lobster Cockroach

The Lobster Cockroach is a medium-sized species with a distinctive mottled grayish-brown pattern, kept worldwide primarily as a feeder insect. Although adults grow wings, they don't fly, and their smooth body surface makes climbing difficult, so escapes are rare even in simple enclosures. Their breeding rate is remarkably high and consistent, making it easy to plan out generation after generation. Calm and shy by nature, they're also enjoyable to simply watch as they move slowly around their enclosure. Hardy and adaptable, they thrive across generations as long as basic temperature conditions are maintained.

About Lobster Cockroach

A medium-sized, grayish-brown mottled cockroach that neither flies nor climbs well, making it escape-resistant. Highly prolific and beginner-friendly as a feeder insect.

7 things to know before welcoming a Lobster Cockroach

1Built-in Escape Resistance
Adults have wings but don't fly, and their legs lack the grip needed to climb smooth vertical surfaces. A simple slip barrier such as petroleum jelly around the upper inside of the enclosure is enough to prevent escapes.
2Highly Prolific Breeding
This species is known for its very rapid breeding cycle, one reason it's among the most widely kept feeder insects. Given suitable temperature and food, colony numbers steadily grow.
3Beginner-Friendly Care
Hardy and adaptable, this species is considered suitable for first-time insect keepers. Basic temperature management is enough to get started without specialized equipment.
4A Roughly One-Year Lifespan
Adult lifespan runs about 365 days for males and 344 days for females, roughly one year. Knowing this generational pace makes it easier to plan breeding and manage colony size.
5Adult Size Up to About 30mm
Adults reach about 28mm (males) to 30mm (females), maxing out around 30mm — a medium-sized species. Since they don't grow especially large, planning enclosure space is straightforward.
6Calm, Shy Temperament
Low in aggression and generally calm, they tend to retreat and hide when disturbed. They're not the type to grow tame enough to handle, but this also means they can be kept with minimal stress.
7Set Up the Enclosure Before Arrival
Having a ventilated enclosure, dimensional hiding spots such as egg cartons, and dry substrate ready in advance makes the transition smooth. It's best to decide on a spot with stable temperature before your roaches arrive.
