Minnesota Flies

 
Order Diptera

Diptera is the order of insects that is characterized as having a single pair of functional wings on the mesothorax and a pair of halteres, reduced, knob-like structures derived from the hind wings, on the metathorax. The order includes true flies, mosquitos, gnats, and midges.

There are about 120,000 described species worldwide, though there are thought to be twice that number of species currently living.

Ferruginous tiger crane fly
   

With over 15,000 described species, the family Tipulidae (crane flies) is one of the largest families of true flies (Diptera). More than 1,600 species occur in North America. The subfamily Tipulinae (large crane flies) contains the largest of the crane flies. In North America, the vast majority of species are in the genera Tipula and Nephrotoma. The genus Nephrotoma (tiger crane flies) contains about 150 described species. The most common of these is ferruginous tiger crane fly (Nephrotoma ferruginea).

“Ferruginous” means reddish-brown or rust colored, but ferruginous tiger crane fly is more often described as orange in color. It is distinguished from other crane flies by the body color, the antennae that are entirely black except for the first two segments, and by a black spot at each end of a groove across the thorax.

Band-winged crane fly
   

Band-winged crane fly (Epiphragma fasciapenne) is a common, easily identified, moderate-sized crane fly. It occurs in the eastern United States and adjacent Canadian provinces east of the Great Plains. Eastern Minnesota is at the western edge of its range. It is found in floodplain woodlands and wooded areas adjacent to swamps.

Like all crane flies, the body is long and slim, the wings are long and narrow, and the legs are very long, very thin, and very fragile. The thorax has a distinct, V-shaped groove on top. The lower jaws each have a very long, antenna-like extension.

Band-winged crane fly is distinguished by the distinctive wing pattern with four bands of bordered brown spots, and by a dark brown band at the very tip of the third leg segment.

Lesser bulb fly (Eumerus spp.)
   

Eumerus is a genus of small hoverflies in the family Syrphidae. With 281 known species, it is one of the largest genera of flies. It is found throughout the Palearctic realm, which includes Europe, Asia north of the Himalayas, North Africa, and the northern and central parts of the Arabian Peninsula. Several Eumerus species have been introduced into North and South America. Three of these are known to occur in the United States: lesser bulb fly (Eumerus funeralis), narcissus bulb fly (Eumerus narcissi), and onion bulb fly (Eumerus strigatus). Collectively, they are known as lesser bulb flies.

Adult lesser bulb flies are black tinged with bronze. They have pale longitudinal stripes on the thorax and silvery-white stripes on the abdomen. The larvae are considered pests. They tunnel into plant bulbs, causing the bulbs to rot. The bulb either dies or produces stunted growth in the following growing season. In some areas, up to 25% of narcissus bulbs are infected.

Long-tailed dance fly
   

Long-tailed dance fly (Rhamphomyia longicauda) is a small, black, long-legged fly. It is commonly found from May to July in deciduous woods near water. The wings are long and black. The head is round with large bright orange or red eyes. On the female, the middle and hind legs have a fringe of long, black, bristly hairs.

Every evening around sunset, males and females collect in same-sex swarms. Females and fly up and down, the behavior that gives this family its common name “dance-flies”. Females cannot hunt for prey. They receive protein from males as gifts in exchange for copulation. They swallow air, filling and extending their abdomen outward, saucer-like, falsely signaling males that their eggs are nearing maturity. The long hairy legs wrap around the abdomen, making it appear even larger. Males are attracted to females that have largest swollen abdomens and hairiest legs. An individual will break off and join the other swarm to select a mate.

Bumble bee mimic robber fly (Laphria sacrator)
   

With 7,003 species in 530 genera worldwide, robber flies are one of the largest and most abundant families of insects alive today. Bee-like robber flies, as the common name for the genus suggests, resemble bees. There are 240 species of bee-like robber flies, 62 species in North America north of Mexico. Few of the species have been given a common name. Laphria sacrator is one of several species famous for being a bumble bee mimic, so “bumble bee mimic robber fly” will stand in for the common name.

Bumble bee mimic robber fly (Laphria sacrator) is a short, robust, medium-sized, bee-like robber fly. It is fairly common in northeastern and north-central United States, including Minnesota. It has a stout thorax and a short abdomen, both partially covered with long yellow hairs making it resemble a bumble bee. It is one of the hairiest of the bee-like robber flies. Adults are to 1 long.

If you do not see a linked page for an insect in the list at left, or the insect does not appear in the list, you can still upload a photo or video as an email attachment or report a sighting for that insect. Click on one of the buttons below and type in the common name and/or scientific name of the insect in your photo, video, or sighting. A new page will be created for that insect featuring your contribution.

 

Capitalization of Common Names

Insect scientific names are governed by the International Commission on Zoological Nomenclature (ICZN). Vernacular (common) names are not. In an attempt to “assure the uniformity of (common) names of common insects” the Entomological Society of America (ESA) published Common Names of Insects and Related Organisms. ESA has no rule or guideline that addresses capitalization of common names. However, the database of common names published by ESA does not capitalize common names. National Center for Biotechnology Information (NCBI) also uses uncapitalized common names. Most other sources, including ITIS, BAMONA, Odonata Central, and the Peterson Field Guides, capitalize common insect names. MinnesotaSeasons.com will adhere to the convention followed by ESA and NCBI.
