perhaps my favourite caterpillars are those of the Evening Brown (Melanitis leda). intensely green and hairy, with a pair of superb burgundy horns!
below is their adult form. as adults, they are crepuscular (only active at dawn and dusk), an unusal trait for an ectothermic insect. this adult was found sleeping well after sunset, perhaps the only way to get close enough for a good photo!
Evening Brown, larva and adult, 2 individuals (Melanitis leda), April '24.
