Palpada is a of 85 of flower flies (hoverflies) in the tribe Eristalini, distributed across the Neotropical and Nearctic regions. are often colorful and -like in appearance. The genus is distinguished from related Eristalini genera by specific morphological characters including uniform pile, pale hairs on the meron, and distinctive wing venation. Larvae are aquatic 'rat-tailed' maggots with extensible breathing siphons that allow survival in low-oxygen environments.

Identification
Distinguished from related Eristalini (Eristalis, Meromacrus, Eristalinus, Helophilus) by: with uniform pile; meron with fine pale hairs in front of or below the ; hind with basal patch of dense black setulae; r2+3 closed before wing margin; and R4+5 moderately to strongly dipped into cell r4+5.
Images
Habitat
occur in diverse terrestrial where flowers are available. Larvae inhabit aquatic or semi-aquatic environments including putrid and organic-rich standing water, rain gutters, and decomposing organic matter in saturated substrates.
Distribution
Neotropical and Nearctic regions (New World tropics and subtropics, extending into temperate North America).
Diet
Larvae filter bacteria and other microbes from organic matter in water. feeding habits not explicitly documented in sources.
Life Cycle
laid in or near aquatic organic substrates. Larvae are aquatic 'rat-tailed' maggots with an extensible breathing siphon (rat-tail) that connects to the water surface, enabling respiration in low-oxygen conditions. Mature larvae seek dry land to pupate; pupal capsule is hard and mouse-shaped in appearance.
Ecological Role
Larvae contribute to decomposition of organic matter in aquatic environments. are , though specific pollination services not quantified in available sources.
Human Relevance
Larvae sometimes encountered in artificial water containers, rain gutters, and water gardens. are respectable visiting wildflowers, orchard blossoms, and landscape plants. Occasionally found in compost and decomposing organic materials.
