NPPF Canto Two--Contrasting butterfly species

[Paul Mackin]

I don't remember if the two butterfly species referred to in Canto Two
have been contrasted with each other.

Taking advantage of Boyd's research,"the Toothwort White happens to be
'dusky white with smoky gray-brown scaling,' and like the Mustard White
with which it was long confused, 'quite shy.'" 

A Toothwort White appears in close proximity  to accounts of Hazel's
ungainliness. This seems to build on the mention of "white butterflies"
in Canto One. 




A Vanessa atalanta does not itself appear in Canto Two (I don't think)
but Sybil is called a dark Vanessa.

On the Vanessa atalanta Boyd quotes a lepidopterist:

"Unmistakable and unforgettable . . . [It} will alight on a person's
shoulder day after day in a garden . . . . In midsummer it is not
unusual to see them chasing each other."
