The fly hovers over the region on which the egg is to be deposited, then darts down, cements it to the hair in an instant, retreats a few feet, hovers again, then deposits another egg. The cap or operculum is pushed off the large end, through which the young grub escapes when the egg is hatched. The eggs hatch in three weeks.
