Raising and Breeding Rice Flour Beetles
The Rice Flour Beetle, Tribolium confusum, is a common pest in many grain-based foods. The traits that make it a pest species – namely, it's short reproductive cycle, exponential growth rate, and tolerance to a wide variety of conditions – also serve to make the Rice Flour Beetle an ideal insect to culture for a wide variety of reptiles and amphibians that prefer smaller foods, especially Poison Dart Frogs.
Rice Flour Beetles are a little over 1/8 inches long when adults, and can live for over a year. Adults lay eggs in Josh's Frogs Beetle Batter, which take about a week to hatch into larvae. Within 6 weeks, the larvae pupate and become adult beetles. Due to their longevity and short maturation time, Rice Flour Beetles can quickly increase their population in a culture.
We culture Rice Flour Beetles on a special media we make ourselves, in order to insure the Rice Flour Beetles we sell are raised on only the highest quality ingredients. Beetle Batter contains all of the vitamins, minerals, and other nutrients Rice Flour Beetles need to thrive, as well as color enhancers that are passed on to your pet reptiles or amphibians.
Choose a container that seals well, but is not airtight. A plastic shoebox works well when culturing Rice Flour Beetles – this is the Rice Flour Beetle culture container of choice at Josh's Frogs. Place Beetle Batter in the container, to a depth of about 2”. Add Rice Flour Beetles to the culture, and ignore the Rice Flour Beetle Culture for a few months. This wait period will give the beetles time to establish in the culture, before you feed any off to your pet reptiles or amphibians. Rice Flour Beetles are tolerant of a wide variety of conditions, but will reproduce faster the warmer you keep the culture (up to about 85F). Do not provide a moisture source – they need a dry culture to do well, and excess moisture will cause the media to spoil. Every year, sift out all of the adult beetles and larvae using a sifter, and replace the old media with fresh Beetle Batter.
Feeding to your Pets
The beetle larvae are usually what is fed to your pets. The adult beetles have chemical defenses that make them unappetizing to many reptiles and amphibians, but some will take them. At Josh's Frogs, we sift out the larvae and feed them to poison dart frogs, bumble bee toads, small tree frogs, and some smaller species of geckos.
The larvae need to be separated from the Beetle Batter before feeding. Use the following steps as a guideline to harvesting and feeding beetles to your pet reptiles and amphibians:
Rice Flour Beetles are an ideal supplemental feeder to a variety of reptiles and amphibians that appreciate smaller foods in their diet. They are very easy to culture and feed out to your pet, making them a must-have for those of you with Poison Dart Frogs or other herps that enjoy small foods. We carry everything you need to culture Rice Flour Beetles for your pets!
