Wasp and teasel water cup

 Wasps make their nests of paper which requires mixing chewed wood with saliva, so they need to drink a lot. These wasps, however, were drinking from a risky source of water. The water-filled cups of teasels, where many insects and other bugs drown, and whose juices increase the teasel seed set. Although the unfortunate prey of the teasel might have just happen to fall in the cups, the lure of available water on a sunny day could also be a reason insects are lured to the cups, and many bees and wasps must fall prey to this carnivorous plant (check the wonderful blog Cabinet of Curiosities for an example). These wasps were lucky, they held on, quenched their thirst and flew away.
