Our Beetles

Life Cycle

Here at the Fox lab we primarily work with bean beetles (Chrysomelidae: Bruchinae). These beetles, commonly referred to as bruchid beetles, are an excellent model system.

Their life history makes for easy lab rearing. Female beetles will glue their eggs to seeds, where offspring will subsequently burrow in and feed until maturation. Adult beetles emerge from seeds, mate and lay eggs, continuing the cycle.

The species we have in the lab do not require food or water, so maintaining colonies of numerous species and using these beetles for experiments is relatively easy.

Bruchid beetles vary between species and across populations within species in many interesting behavioral and physiological traits. Even larval behavior is interesting in these beetles.

These traits make these beetles simple, interesting and exciting to work with in our lab!

Other Lab Insects

Some of our lab members are also working with Bess beetles (Passalidae) and subtropical blowflies (Sarconesia chlorogaster).
