New Techniques for Associating the Stages of Aquatic Insects

(excerpt) The immature forms of many benthic insect species are presently either undescribed or unidentifiable. The result is that associations with corresponding adult forms are often necessary in order to confirm specific and sometimes generic identifications. Specific determination of aquatic stages of insects is prerequisite to adequately understanding the various aspects and implications of autecological specificity and the synecological dynamics of an aquatic system. Wiggins (1966), among others, has adequately pointed out the basic necessity of being able to discriminate between immature aquatic species
