Size It Up Insects answer: September 15
The five Insects silhouettes for September 15, 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 12 ran from a southern wood ant (6 mm) to a luna moth (9 cm). The widest gap was round 4, Southern Wood Ant against House Cricket, at 3.3×; the closest call was round 3, Common Earwig against Large Milkweed Bug, only 1.2× apart — the kind of round that separates a 90 from a 60.
