The Black-veined White was known as Winston Churchill's favorite butterfly.
   They are considered extinct in the British Isles and parts of Scandinavia although they have a very extensive home range elswhere. 
   They prefer open forest, grazing land, orchards. lanes, gardens, meadows and thickets.
   The flight period of the black-veined white is between April and July.

  The adults are quite social and their abundance varies greatly from year to year. 

   Females are commonly larger than males.

   The dorsal side of both forewings and hindwings is a translucent white boldly veined with black.

   The ventral side is similar in the male but the female has brown veining. Moreover, the female loses most of her scales by rubbing her wings together, resulting in an almost transparent appearance.

    The female is distinguished by a brownish coloring on the leading edge of the forewing.

   The male is almost entirely black and creamy white.

   They can be distinguished from other members of white butterflies of the genus Pieris by its distinctive veined wings
