Size It Up Insects answer: October 10

The five Insects silhouettes for October 10, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 37 ran from a booklouse (1 mm) to an Annam stick insect (10.3 cm). The widest gap was round 5, Tree Bumblebee against Peacock Butterfly, at 5.3×; the closest call was round 3, Booklouse against Head Louse, only 2.2× apart — the kind of round that separates a 90 from a 60.
