Sweet on Acrid. Ichneumonid Wasp, Dusona sp., on Euphorbia palustris, Marsh Spurge, Hortus Botanicus, Amsterdam, The Netherlands
Marsh Spurge, Euphorbia palustris, has medicinal qualities that have been known for millennia. Its veins are full of a milky sap that's acrid and can be used as a purgative. But its yellow-green flowers yield pollens and nectars that draw to them insects of many kinds. Here's a Dusona ichneumonid wasp searching for nutrients on a rainy day. You can just see some raindrops at the bottom of the photo.
