No spiracles were found on the body of the larvae.
Open spiracles occur on the prothorax and first eight abdominal segments.
The bases of the setae are no longer distinct but the spiracles appear as a lateral row of brownish spots.
Internally they are hollowed out to form a small cavity, on either side of which lies one of the spiracles.
There were no eyes, antennae or spiracles and the body segments were, for the most part, indistinct.
The setae near the first and the eighth abdominal spiracles have at their bases an incomplete encircling dark ring.
There was no indication of eyes, antennae or spiracles.
The tracheal system of the final instar larva is fully formed, bearing seven pairs of spiracles.
