Emergence traps are several types; terrestrial, aquatic and both types. They are mainly used to trap the emerged adults from immature stages of insects. The aquatic traps sit atop water bodies and trap insects as they emerge to the adult stage (R. Edward DeWalt, ... John B. Sandberg, in Thorp and Covich's Freshwater Invertebrates (Fourth Edition), 2015). There are two major advantages to their use in ecological, biodiversity, and emergence phenology studies: Since the trap collected adults are origined from the cordon off are of the trap, the origin or the source of the adults is indisputable, and if emptied daily, it fulfils several research objectives. For example, it can be known the number of days of incubation period of species of interest under field conditions, insect -  insect interactions, biodiversity of the location, insect - plant interactions under natural conditions, predator - pray or biological control systems study under natural settings etc. Several designs for emergence traps are available (Merritt et al., 2008) and have been used extensively in sampling Plecoptera for ecological studies (e.g., Harper and Pilon, 1970; Masteller, 1983; Kerst and Anderson, 2006).

We have sourced/developed several models of emergence traps for various scientific needs. Please visit the link to know more
