It was July 9th, although Artogeia rapae leucosoma flies throughout the northern 2/3 of Israel throughout the year. They are very common in Tel Aviv as well as in Jerusalem.
This little white butterfly was methodically nectaring in the perennial beds of Ramat Hanadiv, well before 11 AM. My limited experience with Small whites notes that they are easier to approach than the Cabbage whites in North America. They fly more slowly also. This is truer of the populations outside of cities. The Small whites in cities fly faster.
Our female here was appreciated because her appearance filled in the intervals between larger butterflies with more pizzaz.
