They\u2019re good little pollinators (especially the hairier species), although most feed randomly on white or yellow flowers (unlike bumble bees, which target flowers of a particular species on each outing\u2014flower constancy\u2014ensuring that pollen gets delivered to the right place).<\/p>\n\n\n\n<figure class=\"alignright uwm-c-img--right\"><a href=\"https:\/\/uwm.edu\/field-station\/wp-content\/uploads\/sites\/380\/2020\/10\/syrphid-larva20-1brz.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"215\" src=\"https:\/\/uwm.edu\/field-station\/wp-content\/uploads\/sites\/380\/2020\/10\/syrphid-larva20-1brz-300x215.jpg\" alt=\"Syrphid larva\" class=\"wp-image-11831\" srcset=\"https:\/\/uwm.edu\/field-station\/wp-content\/uploads\/sites\/380\/2020\/10\/syrphid-larva20-1brz-300x215.jpg 300w, https:\/\/uwm.edu\/field-station\/wp-content\/uploads\/sites\/380\/2020\/10\/syrphid-larva20-1brz.jpg 704w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/figure>\n\n\n\n<p>Their larvae (maggots) live a variety of lifestyles; some are decomposers, eating decaying organic bits or wet wood; some eat living plant material like ornamental flower bulbs (and are unwelcome in greenhouses), and others, although eyeless and with only rudimentary legs, <a href=\"https:\/\/bugguide.net\/node\/view\/1386581\/bgimage\">prey on small invertebrates like aphids<\/a> <i class=\"fa fa-external-link\"><\/i>.

They can make a soft \u201chum\u201d by vibrating some structures in their thorax that are independent of flight.

After two or three weeks and around 400 aphids, the larvae are ready to form a pupal case inside of their hardened final larval skin (puparium) (looks like a slipper shell), and there they overwinter.<\/p>\n\n\n\n<p>These are Fair-weather Flies\u2014if you see one, it\u2019s probably warm and sunny. Most are also home-bodies, seldom leaving the area where they hatched.<\/p>\n\n\n\n<p>The BugLady found an amazing paper about syrphid fly migration. It\u2019s a known phenomenon among some European species, and it had been recorded on the East Coast of North America nearly 100 years ago, but it had not been noted in the literature since then. In the paper, researchers Menz, Brown, and Wotton discuss a migratory event that occurred in California in 2017 in which it was estimated that hundreds of thousands of syrphid flies passed over a 200 meter-long stretch of trail in 30 minutes.<\/p>\n\n\n\n<p>Here are some of the syrphid flies that the BugLady saw this summer (for most, she\u2019s resisting going out on her usual taxonomic limb and guessing their species). Check them out!
