Two shelters were found to be empty and the other four had 1st and 2nd instar caterpillars less than 10mm. The above image shows the leaf shelter at tip of leaflet.

“On 21st July we opened the shelter to reveal the pupa (above). We did this because the leaf shelter had dried and harden and our previous experiences with other species taught us that this will injure the imago during eclosion.
