This spring is good for migratory butterflies and moths. Besides painted ladies and red admirals which have flown to the Netherlands in large numbers there are also many reports of hummingbird hawk-moths. The crowning touch is the striped hawk-moth which on June 7 was seen in a garden in Velserbroek.
This South European species had been seen for the last time in the Netherlands in 2011.
