Distribution: Central, S and E Spain and the mountains of Morocco.
Identification: Yellow undersides and the patch of orange in
grey-black forewing tips are highly distinctive.
Flight time: Single brooded from mid March to mid June according to
altitude and location.
Habitat: Open flowery grasslands amongst hills. Places dominated by
Cruciferae are favoured. Larvae feed on Isatis tinctoria (Woad) and
Hirschfeldia incana (Hoary Mustard).
Behaviour: A very strong flyer ranging over wide areas. Is attracted
to the flowers of various Cruciferae.
Additional notes: In my very limited experience of the species in
Spain and Morocco it is found only in low numbers and considerable periods of
time may pass without seeing any butterflies. Patience is required, but is well
worth the wait!
