Explanation of Names
From the large-carpenter-bee genus Xylocopa + the Greek ending -oides (-οιδης)- "looking like, like"
Size
♂ 10-11 mm; ♀ 12-13 mm (Smith, 1853--see Remarks)
Identification
A very dark Megachile, resembles a Carpenter Bee, Xylocopa, especially such blue-black species as Xylocopa micans.

Quoting from Bees of Florida: Subgenus Melanosarus Mitchell, 2 species. A neotropical subgenus with 2 species in the USA. M. bahamensis is restricted to SE Florida while M. xylocopoides likely occurs throughout the state.... Megachilidae: Megachile xylocopoides Smith. ... Dates: March to November. Notes: primarily a coastal plain species of the SE USA; extends west to to the western deserts.
Range
Southeastern United States, esp. coastal plain
Season
March-November (Florida). May-September (North Carolina)
Food
The Hosts section on its Discover Life species page lists known floral associations based on specimen records and images. Pollen specialist on Asteraceae.
Remarks
Smith (1853) gave length of male as "5 lines", female "6 lines". If this refers to the English line (1/12 inch, or about 2.1 mm as used by botanists, though sometimes reckoned as 1/10 inch!), that gives 10-11 mm for the male, 12-13 mm for female.
