Nectar-foraging
Guides
Cryptocheilus idoneum
Cryptocheilus idoneum is a species of spider wasp in the family Pompilidae, first described by Nathan Banks in 1910. Like other members of its genus, it is a solitary wasp that hunts spiders to provision nests for its larvae. The species has been documented in western North America, particularly in arid and semi-arid regions. Observations indicate adults visit flowering plants for nectar, including invasive saltcedar (Tamarix).
Lycastrirhyncha nitens
Lycastrirhyncha nitens is a hoverfly species (Diptera: Syrphidae) first described by Bigot in 1859. It is known from floral visitation studies on Pontederia sagittata (arrowhead water hyacinth), where it exhibits temporal variation in foraging behavior correlated with nectar availability. The species has been documented in wetland habitats across Brazil, with GBIF records indicating presence in all 26 Brazilian states and the Federal District.
