The Orange-tip is a fairly common butterfly in spring and early summer.
They are common in late April on Fleam Dyke, especialy at the Balsham end on large sheltered patches of Garlic Mustard.

There is just one brood per year. The larval foodplants are Ladies Smock (wild at Roseland House) and Garlic Mustard, common beside hedges and in light woodland.
This species over-winters as a pupa which hatches in the following spring.
