Summary
1. A single hanging vertical line of the snare appears to be secreted at one time, and there is no evidence that a pre-existing line is cut and a new piece joined, so as to make a combined line. In all cases the lines are lowered from near the main runway, and there is no evidence that a line is first fixed and then secreted and hung from the side or from below.
2. In cases where the snare lines are about an inch in length, it is certain that the worm climbs down the necessary distance to reach the snared prey. The latter is not recovered from the runway by the worm rolling the lines around its head end, or by gathering relevant lines in its jaws.
3. The mucus droplets as secrated first flow around the head, and the droplets are placed in situ, by the worm pulling its head out of the mucus.

4. What appeared to be an adult worm was caught and fed for six weeks before it pupated. It seems obvious that glow-worms mature slowly at this period.
5. The glow-worm about to pupate clears away the nearby sticky lines, leaving a clearance of at least 20 mm on each side. It then becomes suspended on a silken thread usually about the length of its body. The clearance of sticky droplets, and the suspension of the pupa, provide a certain degree of safety for the pupa, and for the adult at the time of emergence.
6. After three days, the suspensory cord is seen to be yellowish in colour. It finally becomes chitin-brown in older pupae. The cord appears to be formed of silk threads gummed by mucus.
7. The suspensory thread is not the converted runway. It is a new formation which has a main dorsal thread attached to the meso- and meta-thoracic regions, and appears to form a part of the pupa. However, it separates from the thorax if roughly handled, the dorsal thread breaking at its junction with the thorax.
8. The single male pupa observed glowed as brightly as neighbouring larvae. It doused at the same time as the latter, but did not light up when they did. Unlike the larvae it glowed faintly for periods. It lighted up in a few seconds when the tin container was opened in the morning.
