Is this fly famous? Empididae

Dance flies of the family Empididae have escaped Crumby so far. But now, after a little help, those dance flies have come under the scrutiny of the Junior Ovate. However, dance flies are apparently not well known from these parts. That may be because gentlemen in Tejas would never construct a balloon from frothy anal secretions to attract females. Or maybe they would, and like much else, never thought of that solution.

Yes. I have designed this balloon just for you dear. Look inside. Inside the frothy anal secretions of my balloon are prizes. Those prizes include a ring plus an economy SUV. And you my dear may obtain those prizes just by agreeing to have sexual intercourse avec moi.

I don't know if this Empidinae constructs balloons. The fact is, given the available scanty information, Crumby can not determine its genus, yet.
