The larva is very similar to that of D. winnemana as described above, but is slightly smaller. The spiracular disk ([fig. 9]) has the dark markings much more extensive. The mark of the lateral lobes is contiguous with the spiracles and is also closely approximated to the large triangular brown mark on the disk. There is a large transverse rectangular mark occupying the inner face of the dorsal lobe. The marking of the ventral lobe is about as in D. winnemana.
