We’re in Osaka, Japan, living in a 10th floor apartment, so whatever laid that egg was a good flier. It’s about 7 cm long, and chowing down on raspberry bushes. Any idea what it will become? The picture was taken about a week ago (May 24th).

This appears to be an Inchworm or Spanworm in the Moth family Geometridae. Most caterpillars in this family have only two pairs of prolegs which causes them to move in a most characteristic manner, where the caterpillar stretches out with is true legs and then moves the entire hind section in one step, inching along and causing the body to loop. We are not certain of the species. Most Geometrid Moths are dull in color, but some are quite colorful.
