Empis tessellata is the largest British Empis species. Dance flies are completely harmless and do not bite people or animals. These dance flies can be found on various plants on moist meadows, on forest edges, on clearings and lightly wooded areas. Þessi grábrúna fluga er mest á ferðinni nálægt skóglendi þar em hún flýgur um á milli hvanna og blómstrandi trjáa þar sem þær veiða skordýr á flugi. Það má oft sjá þær fljúga þunglega með flugur sem eru oft stærri en þær sjálfar. Við mökun lítur kerlingin ekki við karlinum nama hann færi henna feita flugu - og þá first fer mökun fram. Kerlingin verpir síðan í jarðveginn þar sem lirfurnar lifa á að égt smáskordýr í moldinni. Flugan hefur enska nafnið dansfluga vegan þess hvernig karlinn dansar fyrir framan kerlinguna með mökunargjöfina.

Breddur (Empididae) Á Íslandi finnast sjö tegundir af þessari ætt. Strandflugan (Clinocera stagnalis) er ein þeirra. Hún er algeng um allt land, einkum við strendur stöðuvatna og í straumvötnum. Flugur strandflugunnar eru blágráar að lit. Þær hlaupa gjarnan um á yfirborði vatnsins, en fljúga lítið. Lirfurnar eru rándýr, lifa á bitmýs- og rykmýslirfum. Þær eru ormlaga, mjókka fram á við og hafa 6-8 pör fóttota og hárbrúska á afturenda. Höfuð er ógreinilegt, til að klófesta bráð skjóta lirfurnar fram sterkbyggðum kjálkum. Lífsferlar strandflugunnar eru lítt þekktir hérlendis. Hún finnst allvíða um landið og er mest á sveimi í júlí. Lesa meira: http://gamli.veidimal.is/default.asp?...

These large dance flies have a strongly black bristled body.The long legs are varying in color, usually they are red-yellow with black thighs. The brown-tinged wings have dark brown veins and rusty-yellow costal margin. The head is small and almost spherical with black antennae, large brown eyes and a long pointed proboscis

Adults can be seen from April to August. Apparently only adult males are predatory on other insects, but also larvae are predatory. Adults mainly hunt Diptera or other small insects, but they also feed on the nectar of flowers. especially of umbellifers. Before mating, the male catches a prey to present as a gift to the female. Only then the mating takes place. The creamy-yellow larvae live underneath the ground and in leaf litter. See more: https://en.wikipedia.org/wiki/Empis_t...

They can also be found hunting for small insects on and under vegetation in shady areas and on front porches at night (dance flies are very effective mosquito-predators, but both genders may also eat nectar). See more: https://uwm.edu/field-station/dance-f...

The head is more or less spherical, with a visible neck; eyes large, often restricting the face. Proboscis well developed and rigid, and often wielded with abandon by these little predators.

Several of the Empis species are "balloon makers." That is, the male flies capture an insect and enclose it in a frothy bag. The male carries this package around with him as a lure to entice the female to mate. (Females of many species seem to require something of this sort. Wonder if a "bug balloon" would work with H. sapiens?) Some species dispense with the froth. Empis barbatoides males capture little insects, usually weaker flies like bibionids (March flies), and dangle them in front of females as a preface to courtship. Others trick their intended with an empty ball of silk. Larvae, according to the Diptera Catalog, are "usually found in rich, moist soil. See more: https://crawford.tardigrade.net/bugs/...
