"When daisies pied and violets blue,
And lady-smocks all silver-white."

Possibly Hood was thinking of the Orange Tip when he wrote the lines
that seem so well suited to them:

"These be the pretty genii of the flowers
Daintily fed with honey and pure dew."

A story is told of an undergraduate who united the hind wings of a
butterfly to the body and fore wings of one of a different species,
and, thinking to puzzle Professor Westwood, then the entomological
authority at Oxford, asked if the Professor could tell him "what kind
of a bug" it was. "Yes," was the immediate reply--"a humbug!"

One of my schoolfellows, a boy about eleven, at Rottingdean school,
and quite a novice at butterfly collecting, met a professional
"naturalist" on the Warren at Folkestone, who inquired what he had
taken. "Only a few whites," said the boy. The man looked at them and,
eventually, they negotiated an exchange, the boy accepting three or
four others for an equal number of the whites. On reaching home he
found that he had parted with specimens of the rare Bath White,
_Pieris daplidice_, for some quite common butterflies. The Bath White
is not recognized as a British species, Newman supposing the specimens
taken in this country to have been blown over or migrated from the
northern coast of France, as they have been rarely met with away from
the shores of Kent and Sussex.

It is surprising to find so many people who seem unable to exercise
