Size It Up Insects answer: September 25

The five Insects silhouettes for September 25, 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 22 ran from a seven-spot ladybird (6.6 mm) to a privet hawk-moth (10.5 cm). The widest gap was round 4, Convolvulus Hawk-moth against Common Darter, at 2.5×; the closest call was round 3, Seven-spot Ladybird against Marmalade Hoverfly, only 1.5× apart — the kind of round that separates a 90 from a 60.
