Notes on theMichigan Species ofPantala

There are two species of Pantala in North America,both occur within our range (see maps below). Larvae are pale,greenish with light brown markings. Like that of other highlymigratory dragonflies, larvae are active, fast-growing predators thatadapt well to temporary lentic habitats, including those created byman. Larval development and descriptions of each instar forP. flavescens was thoroughly treated by Lamb (1925,1929) and summarized by Huggins and Brigham(1982). Prey varies from smallinvertebrates and probably zooplankton in earlier instars, tomacroinvertebrates and even small fish in later instars (Lamb 1925, Warren 1915). Time period for larval development probably variesconsiderably, depending on temperature and food availability, amongother factors, and has been reported from 145 to as little as 36 days(Lamb1925, Warren 1915, Bick1951). It is not known whether larvaeoverwinter in Michigan.
