Size It Up Insects answer: October 4
The five Insects silhouettes for October 4, 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 31 ran from a common fruit fly (2.5 mm) to a monarch butterfly (9 cm). The widest gap was round 3, Common Fruit Fly against Click Beetle, at 3.6×; the closest call was round 2, Small Tortoiseshell against Migrant Hawker, only 1.2× apart — the kind of round that separates a 90 from a 60.
