摘要

描述

Varroa destructor, the leading cause of beekeeper angst. This relatively large mite parasitizes honeybees from adults to larvae. Crab-like aren't they? Specimen provided by Krisztina Christmon from the University of Maryland where she studies the life history of these tricky beings. Oh, that is the tip of an insect pin you see in the picture. 23:43, 12 February 2020 (UTC)23:43, 12 February 2020 (UTC){{{{{{0}}}}}}23:43, 12 February 2020 (UTC)23:43, 12 February 2020 (UTC)

We Are Made One with What We Touch and See

We are resolved into the supreme air, We are made one with what we touch and see, With our heart's blood each crimson sun is fair, With our young lives each spring impassioned tree Flames into green, the wildest beasts that range The moor our kinsmen are, all life is one, and all is change.

       - Oscar Wilde
