The suborder Zygoptera (Damselfiles) contains some of the most lithe and elegant insects in the world. Their inspiring grace is only eclipsed by their utility to man. Effective at helping to control dangerous insect pests and vectors of disease in both their adult and larval phase, few insects are more welcome or appreciated the world over.
The species used are chiefly species from South Amercia, S.E. Asia and the USA.
