The Featured Creatures collection provides in-depth profiles of insects, nematodes, arachnids and other organisms relevant to Florida. These profiles are intended for the use of interested laypersons with some knowledge of biology as well as academic audiences. This document provides a detailed profile of the hydrilla tip mining midge, Cricotopus lebetis. It covers the midge's distribution, physical description, life cycle, host plants, and its potential as a biological control agent for hydrilla. The midge larvae mine the meristematic tissues of hydrilla, disrupting shoot growth and preventing new stems from reaching the surface. The article emphasizes the importance of integrated pest management and discusses the challenges and strategies for mass rearing and release of the midge to control hydrilla infestations.
