Abstract
A size selective underwater light trap isdescribed. Trap records
indicate that the trap iseffective in taking a wide variety oforga-
nisms within size limits that can be set by the experimenter.
Introduction
Hungerford et al. (1955) described the construction and
operation of an underwater light trap. Their records indi-
cate that such traps are very efficient in the capture oflarge
numbers of aquatic insects. Data from Engelmann
(1974) and Engelmann & Tobisch (1972), indicate that
such traps take virtually all orders of aquatic insects as
well as mites, spiders, fish and salamanders. Traps with
such catholic capture results make it necessary for the
experimenter to sort through great numbers of organisms
