Insect egg (caterpillar?) on unknown plant.?

Oh!... this is a great opportunity to raise a erfly!... Take the chance!... Gather the catterpillars and put them in a safe box with a transparent lid... Put the foodplant inside and just watch... Remember to change the withered plants with new ones often... With proper care (its easy trust me, I've raised LOTS of erflies this way!) the caterpillar will grow and pupate and a (hopefully!) beautiful erfly will emerge...
