Compound eye large dance fly (Empididae), made with magnification factor 7 and f/9...Empididae is a family of flies with over 3,000 described species occurring worldwide, but the majority are found in the Holarctic. They are mainly predatory flies like most of their relatives in the Empidoidea, and exhibit a wide range of forms but are generally small to medium sized, non-metallic and rather bristly...Common names for members of this family are dagger flies (referring to the sharp piercing mouthparts of some species) and balloon flies. The term "dance flies" is sometimes used for this family too, but the dance flies proper, formerly included herein, are now considered a separate family Hybotidae...Some Empididae, such as the European species Hilara maura, have an elaborate courtship ritual in which the male wraps a prey item in silk and presents it to the female to stimulate copulation. Empidid larvae are also largely predatory (although some are scavengers) and occupy a wide range of habitats, both aquatic and terrestrial (source: Wikipedia).
