On September 28, the association that has time to watch butterflies announced that the southern small white (Pieris mannii) of the Pieridae family has been spotted and photographed at Fort Sint Pieter near Maastricht, Limburg. Hardcore butterfly enthusiasts knew this day was coming, as this species was slowly making its way north.

The big question was whether it would show up in Belgium or the Netherlands first. The cosmos amusingly forced a compromise by having a Belgian man discovering the southern small white in the Netherlands.

According to Wikipedia, the southern small white is usually found in South Europe, Asia Minor, Morocco and Syria.
