Adult was obviously very active after eclosing and did a great deal of damage to its wings.
Possibly this species, seen several times at the house 250m away from the site of the larvae?

Finally a pupa! Very active.
25 Oct: Long, tidily constructed tube sticking up from a hole in the ground. No inhabitant activity seen.
The tube was removed and left next to the hole.
26 Oct: A new small tube had been started overnight. There had been some fiddling with the original tube.
27 Oct: A portion of the original tube had been cut off and attached to the short new tube.
29 Oct: Three more burrows and grass tunnels found in a 2x2m area around the original burrow.
The tube was removed from burrow 2. On re-inspection 4hrs later the burrow entrance had been concealed by cut grass pieces.
The tube was removed from burrow 4 - on re-inspection the entrance had been sealed with a very strong lattice of transparent threads.
30 Oct: Five more tubes found, total now 9 in an area of 4x4m.
20 Nov: Attempted excavation of larva resulted in the lower half of a larva being recovered.
21 Nov: Larva seen (and photographed) moving bits of vegetation in the early morning (04:53) Video: https://www.youtube.com/watch?v=LoVSiIsogcs
22 Nov: tubes continue to be repaired or replaced.
23 Nov: larva excavated in the early morning and housed, with its host plant, in a bucket covered with shadecloth.
28 Nov: a thorough search of the thick grass was done and 5 more tubes were discovered in the 4x4m area. Interestingly, one tube is considerably narrower than the regular sized tubes and another was found of an intermediate size.
10 Dec: no signs of the captive larva, found it dead and dry under the host grass.
18 Jan: Larvae still active - two damaged tubes were repaired on 18 and 22 Jan
16 March: live larva collected
