The painted lady is a common butterfly. It
is found on all continents except South America and Antarctica. It is a notable
migrant and in some years tens or hundreds of thousands appear suddenly in the
Maltese countryside only to disappear some days later.
In the USA this species is known as
Cosmopolitan. In Maltese it is known as farfett
tax-xewk.
When resting on the ground with its wings
closed the painted lady can be very well camouflaged and difficult to see but
it often spends time sunbathing with its dark orange wings open in full view of
any predator that happen to be in the vicinity as well as to potential mates.
Adult lives from two to four weeks but
during their brief life some manage to travel from North Africa to northern
Europe. Spring migration takes place every year but we do not see it annually
because the exact route taken is determined by weather and wind direction.
Until recently it was believed that the
movement is in one direction only but research is indicating that in autumn
there is another migration to the south. The southern movement takes place at
very high altitude and is being studied by means of entomological radars. Research
has shown that these butterflies use the sun to orientate themselves so as to
be able to keep a straight-line path.
The caterpillars can be found feeding on
mallow plants (ħobbejż), wild
artichoke (qaqoċċ tax-xewk) and
borage (fidloqqom).
The painted lady is related to the red
admiral (farfett tal-ħurrieq),
another common butterfly. It also has other close relatives namely the
Australian painted lady, the American painted lady which is usually found in
mountainous areas of North America and the west coast lady which can be found throughout much of the western US and
south western Canada .
