A male adult of the New Zealand glow-worm, Arachnocampa luminosa. This is a rare photograph of an elusive fly, but its appearance is typical of land-midges all over the world.
(After OLDROYD, 1964)
In this photograph we can clearly see that the basal trunk of the Media is present and well-developed. It is not replaced by the cross-vein tb1. So it is doubtful whether this form belongs to the Fungivoriformia. Further we can see the unbranched Radial Sector.
