Cover art for Ecdysis lyrics by Mirah And Spectratone International

Pretty sure it's about the caterpillar stage of the monarch butterfly becoming a butterfly. The caterpillars are yellow and black and they hang upside down and form a J and then form the chrysalis that's mostly green but it looks like it has some golden color in it too. And imago is the final, usually winged, stage of an insect. The butterfly stage.
