Melissodes rivalis, the rival long-horned bee, is a species of long-horned bee in the family Apidae. It is most commonly found in northern parts of the United States, as well as Canada. [1][2][3][4] This species is native to Montana, although it has also been spotted in other northern states including Idaho, Wyoming, and Minnesota.[5] As a part of the Eucerini tribe, this species' male has unusually long antennae, as well as being a solitary bee, therefore, it does not create colonies or store honey, though some may form large aggregations.[6][7] Unlike colonial bees, the female Melissodes rivalis constructs and provisions her own fossorial nest without outside help, while males tend to sleep in flower heads.[7][8]
Melissodes rivalis is a member of the Eucerini tribe which includes more than 780 different bee species split up into 32 different genera making this tribe the most diverse in the family Apidea, though the distinguishing line between each genera remains ambiguous with many small and still unclear having the bulk of the species belong to the same five genera including Melissodes having over 140 different species. [9][10]
Description and identification
Melissodes rivalis is a long-horned bee placed in the tribe Eucerini, the "true horned bees"; they are 11–14 millimetres (0.45–0.55 in) from abdomen to thorax, with the male's antennae occasionally being longer than their bodies.[11] Like other true horned bees, its body and legs are covered in a layer of setae made for collecting pollen.[7] Melissodes rivalis have an elongated body slightly resembling a common honey bee, be it smaller, with a dark gray abdomen stripped with white or cream colored hairs.[7] These bees have hyaline wings with their apical margins being a faintly cloudier beige.[11]
