“The caterpillars ... exhibit(ed) great restlessness and a desire to escape from confinement; moving about incessantly for two days until they became exhausted. One finally spun its cocoon beneath a piece of dried bark, attaching to it sundry small twigs – the other selected the corner of the feeding cage.” Description from AW Scott, ‘Australian Lepidoptera and their Transformations’, Volume 2, Plate 19 (1890-1898).
