Genus Mallota

Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Class Insecta (Insects)
Order Diptera (Flies)
No Taxon (Aschiza)
Family Syrphidae (Syrphid Flies)
Subfamily Eristalinae

Genus Mallota
Other Common Names
Bee-like Hover Fly
Explanation of Names
Author of genus is Meigen, 1822. Mallota appers to mean "of Mallus", which was a classical name for a region of Cilicia in Asia Minor. Crates of Mallota was a Greek philosopher, and poet/playwright as well, though the latter was possibly a different person. Perhaps there is a connection there, though it is not obvious. Speculation: Greek actors used masks--a reference to mimicry in this genus? (Based on Internet searches.)
Numbers
Neartica and Arnett (1) list 11 North American species.
Size
11-19 mm
Identification
Adults are bumblebee mimics with very large hind femora. Resemble closely-related Eristalis in overall form.
Larvae have a tube-like breathing siphon at the tip of their tail.
Range
Includes eastern North America. M. bautias is found in northeast, southeast, and Texas. (1) M. posticata appears to be widespread in east: noted from Minnnesota, Oklahoma, North Carolina, Ontario.
Habitat
deciduous forests and edges; adults frequently visit flowers
Season
Spring, early summer. Perhaps late summer and early fall in south?
April-June, August-October (M. posticata, North Carolina).
May-June (M. posticata, Oklahoma, Minnesota), June-July (M. cimbiciformis, Minnesota).
April-June, July (M. bautias/facialis, Oklahoma).
May-July (M. bautias/posticata, Ontario).
Food
larvae are deposit feeders in water-filled tree holes
Remarks
Males show hilltopping behavior - they congregate in open areas of high elevation (hilltops, moraines, escarpments, clifftops) and wait for females to arrive to mate.
