.....Izzie, it does not feel like Autumn yet - still quite hot and rainy for the last few weeks. I don't know whether I have the patience for a time-lapse series and it would have been difficult under the circumstances. I had hoped to get a shot of it emerging though.
I identified the unknown one as a yellow migrant. The caterpillars are fussy about the trees they feed on and we happen to have a
cassia brewsteri which is one of their favourites. They have quite pretty flowers earlier but have no flowers and few leaves left now.
