A. Butterflies & Moths
B. Geometer moths (GEOMETRIDAE)
Geometer moths (named for the way in which their larvae move in a weaving fashion as if measuring the earth) form a large family. Their wings are usually held flat. Although these moths appear very much like butterflies, they are indeed moths and are usually nocturnal.
C. Lime-speck Pug (Eupithecia centaureata)
The Lime-speck Pug is a relatively common moth with a distinctive appearance, mostly white save for a black patch on the leading edge of each forewing. It's a small moth with a wingspan of between 20 and 25 millimetres. This species overwinters here as a pupa.
Because there's a visual resemblance between this moth and bird dropping, it's thought it might have an inbuilt survival advantage.
