Mayflies Zoom In 1

A Tisza "Flower"
Photograph by József L. Szentpéteri

That's what biologist and photographer József L. Szentpéteri calls this frenzied circle of male mayflies, all trying to mate with a single female. On Hungary's Tisza River the annual summer emergence of the insects is known as the Tisza Blooming. Three years ago many feared a Tisza Extinction. In January 2000 a series of toxic spills from Romanian mines contaminated the Tisza, killing wildlife and more than a thousand tons of fish. The mayflies apparently survived because their larvae were buried deep in mud on the bottom, and, a few weeks later, a major flood purged many of the pollutants. (For more see Szentpéteri's Field Notes.)
