Quote from en.wikipedia.org/wiki/Platysto…
Signal flies are very variable in external appearance, ranging from small (2.5 mm), slender species to large (20 mm), robust individuals, often with body colours having a distinctive metallic lustre and with face and wings usually patterned with dark spots or bands.The head is large. Frontal bristles on head are absent. Two orbital bristles are on the head. The frontal stripe is
pubescent and the arista is more or less long and pubescent. The antenna1 grooves are deep and divided by a median keel. Radial vein 4+5 bears bristles. The costa is without interruptions and the anal cell is elongated, bordered on outer side by an arcuate or straight vein. The abdomen of male has five visible segments and the female has six.

Many bizarre forms of morphology occur in this family. Heads and legs (fore legs especially) may be oddly shaped, extended in various ways or with adornments, all of which serve to supplement agonistic behaviour. Such behaviour underlies social and sexual interaction between individuals of the same species of signal flies, first researched in Australian species of the genera Euprosopia image and Pogonortalis[2]

In males of Pogonortalis, the length and degree of development of hairs (setae) on the lower facial area, together with widening of the head, facilitates territorial dominance[3] by head-butting and rearing-up behaviours. Head-butting is taken to the extreme in the Australasian genus Achias,[4][5] in which species have the fronto-orbital plates expanded laterally to produce eyestalks.

Development of body structures is prevalent in the Afrotropical and Oriental subfamily Plastotephritinae,[6] including 9 different types of modification in 16 genera.[7]

Shooting at night helps :) But only for a click or 2 before they fly off.
