The plant both attracts insects for pollination and traps and digests insects.  Though this species has not been well studied, other species are known to have mechanisms for keeping these separate -- eating your pollinator is not a good plant survival strategy.  On study suggests that the primary separation mechanism is raising the flowers well above the sticky stems so that the pollinators don't get trapped.

Sweat bees (Agapostemon), bumble bees (Bombus), syrphid flies, and meloid beetles have been listed as pollinators.

Native Habitats:Savannas, bogs, moist disturbed ruderal areas (selected roadside swales), wet flatwoods

General Comments:A similar species, Drosera filiformis is rare in the Florida panhandle and disjunct from northeastern US populations.  In Florida, it is restricted to the Sand Hill Lakes region of the Panhandle and occurs along the fringes of those sandhill lakes.  At one time, Drosesra tracyi was called Drosera filiformis var. tracyi.  They are now considered to be different species.
