Although few predators are fast enough to capture adult tiger beetles, the larvae and eggs are vulnerable to predators ranging from grackles and moles to sandpipers and skunks. Some tiger beetle species can be found in trees, but the vast majority are ground-dwellers. When the beetle larvae hatch they are capable of hunting on their own.

Although few predators are fast enough to capture adult tiger beetles, the larvae and eggs are vulnerable to predators ranging from grackles and moles to sandpipers and skunks. The larvae of the Green tiger beetle hatch in burrows made by the adults in sandy soil, and wait at the entrance to ambush passing prey.

No information exists on type of prey consumed by adults or larvae (COSEWIC 2008); however, tiger beetle larvae in general feed on other insects and arthropods (Pearson and Vogler 2001, Pearson et al. Your beetles should be provided with a heat source, and the desired temperature varies based on the beetle species. About Land Invertebrates in Missouri Neil F. Hadley, C. Barry Knisley, Thomas D. Schultz, David L. Pearson, Water relations of tiger beetle larvae (Cicindela marutha): correlations with habitat microclimate and burrowing activity, Journal of Arid Environments, 10.1016/S0140-1963(18)30817-6, 19, 2, (189-197), (1990).
