Size It Up Insects answer: October 11
The five Insects silhouettes for October 11, 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 38 ran from a common house mosquito (5 mm) to a blue morpho (14 cm). The widest gap was round 5, Blue-tailed Damselfly against Southern Wood Ant, at 5.2×; the closest call was round 3, Migrant Hawker against Emperor Dragonfly, only 1.2× apart — the kind of round that separates a 90 from a 60.
