Morning Glory Bees,Ìý°ä±ð³¾´Ç±ô´Ç²ú³Ü²õÌý¾±±è´Ç³¾´Ç±ð²¹,Ìýare rare, solitary bees that specialize on the pollen of morning glory flowers (±õ±è´Ç³¾´Ç±ð²¹Ìý²õ±è±è.). This bee is relatively large, over a half inch long and it is covered in branched hairs used for pollen-collecting. Until very recently, morning glory beesÌýhad only been found in eastern North America, overlapping with the range of its host plant, Man of the Earth Flower (±õ±è´Ç³¾´Ç±ð²¹Ìý±è²¹²Ô»å³Ü°ù²¹³Ù²¹).ÌýDuring wild bee surveys conducted on Å·ÃÀ¿Ú±¬ÊÓƵ’s Eastern Plains,ÌýÅ·ÃÀ¿Ú±¬ÊÓƵÌýMuseumÌýstaff collected six Morning GloryÌýBeeÌýspecimens, expanding the previously known range of this speciesÌýby over 600 miles westward1. Moreover, finding six specimens in two Å·ÃÀ¿Ú±¬ÊÓƵ counties suggests there is an established population of Morning Glory Bees in eastern Å·ÃÀ¿Ú±¬ÊÓƵ, which had never been comprehensively surveyed for wild bees until 2013.ÌýÌý
Man of the Earth Flower does not occur in Å·ÃÀ¿Ú±¬ÊÓƵ, but another closely related species – Bush Morning Glory (±õ±è´Ç³¾´Ç±ð²¹Ìý±ô±ð±è³Ù´Ç±è³ó²â±ô±ô²¹) – was found where the bees wereÌýcollected9.ÌýThis suggests that this specialist bee does not limit its diet to a single species—ratherÌýitÌýuses several species in the morning glory genusÌýIpomoea.ÌýMan of the Earth Flower and Bush Morning Glory bloom only very early in the morning, which is the only time Morning Glory Bees are found in flight2. Few bees fly so early in the morning, and entomologists rarely survey in these early hours,Ìýperhaps why the Morning Glory Bee remained undetected in Å·ÃÀ¿Ú±¬ÊÓƵ for so long!ÌýSurveys of previously unsampled rural lands can reveal missing puzzle pieces for our understanding of insect distribution and abundance, and museum collections preserve these puzzle pieces for future research3. The understanding and preservation of biodiversity is more important now than ever before, as the earth undergoes rapid climate change and habitat degradationÌýthatÌýresults in the loss of species diversity.Ìý
Longhorn beesÌý(note the long antennae on the pictured bee)Ìýare solitary, meaning they do not have colonies with queens, workers and drones, like the better-knownÌýhoney bees. Morning Glory Bees, like all bees, develop through a process called complete metamorphosis passing through four main stages: egg, larva, pupa, and adult. After mating, a single mother carries out all nesting duties. In the summer, she collects pollen from morning glory flowers,Ìýwhich is then mixed with floral nectarÌýdeposited into a nest she digs in the ground. When enough pollen and nectar have been collected, the mother lays an egg on top of this food resource for her babies and seals the nest. She will lay several eggs, repeating these steps for each egg. The eggs will hatch into larvae in the summer and these larvae feed on the pollen and nectar supply. When the supply is depleted just before winter, they mature into pupa. Upon the arrival of summer when morning glory flowers begin to bloom, adult bees will emerge from their nests and the cycle will begin anew.
