Margined Calligrapher
Toxomerus marginatusAlso known as Margined Calligrapher Fly, Margined Calligrapher Hoverfly
Margined calligraphers are tiny, industrious hoverflies that mimic wasps to deter predators while remaining entirely harmless to humans. Adults spend sunny days hovering motionless before darting to blossoms where they feast on protein-rich pollen and sugary nectar. Their voracious larvae act as exceptional natural pest control, consuming soft-bodied insects like aphids and thrips.
