Agrius convolvuli Finally Pupates

Agrius convolvuli Finally Pupates
It's been my experience that this species of Hawk Moth may take a long time to actually complete the pupation process. If this is typical behaviour in the wild, then I surmise mortality would be high.

Of the 5 caterpillars successfully raised, 2 pupated promptly whilst 3 have taken approximately 3 weeks to complete the task at hand!

I experienced this behaviour with 2 Agrius convolvuli caterpillars earlier in the season. I used unprocessed bran as bedding in their case. Thinking the bedding may be responsible for the pupation delay, I decided to use unfertilised potting mix this time. It's made not one bit of difference, apparently! :-)

They remained on the surface like this for almost the entire time and over the last couple of weeks, permanently.

UPDATE: A moth emerged from one of these pupae on the 19/1/2012.
