Eurytides protesilaus nigricornis - the Zebra Swallowtail
30x14x6cm frame (black)
Swordtails such as Eurytides protesilaus nigricornis are migratory in behaviour, following river courses as they travel. Males can often be seen gathered on sandbanks, filter-feeding on dissolved minerals by continually pumping water though their bodies.
This species invariably congregates in small groups of up to about 15 other Swordtails, either entirely of its own species, or more frequently with other Leptocircini such as Eurytides dolicaon and Protesilaus protesilaus. These groups are usually well separated from groups of Pierids or Nymphalids feeding on the same sandbank. The entire group usually face into the breeze. This specimen originates from Brazil.
