Mayfly With Springtail Hitchhiker: Amber Specimen -- 16 Million Years Old -- Reveals Unknown Animal BehaviorsOct. 17, 2012 — Stunning images, including video footage, from a CT scan of amber have revealed the first evidence of any creature using an adult mayfly for transport.
Researchers at the University of Manchester say this 16-million-year-old hitchhiker most likely demonstrates activity that is taking place today but has never previously been recorded.
Entombed in amber the tiny springtail can be seen resting in a v-shaped depression at the base of one of the mayfly's wings. It appears to have secured itself for transport using its prehensile antennae.
