This publication (part of the Featured Creatures collection, which profiles insects, nematodes, arachnids and other Florida organisms for interested laypersons with some knowledge of biology and for academic audiences), describes the sandhills longhorn bee, Epimelissodes aegis (LaBerge), a solitary bee known to pollinate sunflowers and related plants. It includes facts about its distribution, biology, and economic importance, and lists its host plants. Members of the genus are found throughout North and Central America, typically burrowing in sandy or well-drained soils. There are currently 20 species across four subgenera, but nesting biology has been described for only five of these, including Epimelissodes aegis. All known species in the genus are hosts to kleptoparasitic bees in the genus Triepeolus, which lay their eggs in the nests of other bees and rely on stolen pollen and nectar provisions to rear their offspring.
