An Introduction to the Identification of Chironomid Larvae.
Mason, William T., Jr.
This publication is an introductory guide to the identification of Chironomid (Midge) larvae. The larvae of these small flies are an important link in the food chain between algae and microinvertebrates. As a family, the larvae exhibit a wide range of tolerance to environmental factors such as amounts and types of pollutants. Much of this publication consists of photographs of the cleaned sclerotized head capsules of the common Chironomid genera. A total of 58 genera in four subfamilies are pictured. Several pictures are included for each genus and captions indicate magnification and identification characteristics. The general characteristics of the larvae, methods of preparing the head capsules for photography, a key to the subfamilies, a key to the genera, distinguishing head capsule characteristics, and a list of genera are presented. References are included. (MR)
