Mediterranean white-banded spider
Evarcha jucunda is a species of jumping spider. It occurs naturally in the Mediterranean region, but was introduced to Belgium. It is also sometimes found in German greenhouses. Typically, it shows a large white or yellowish band surrounding the head region and a smaller one at the anterior end of abdomen. Males are black with a white line around their head and the top of their abdomen, which is brown.
The species name is derived from Latin jucundus "pleasant".
