Surprise! Cricket Pollinates Rare Orchids
.Video captured on Reunion Island, east of Madagascar, found a previously unknown species of cricket sneaking in at night and helping one species of orchid reproduce.
In this highly unusual role, the cricket is apparently filling in the part of a specialized moth that normally pollinates such flowers. But on this island, these moths are not found. So the finding offers a striking example of how species -- such as the flowering orchid -- figure out a way to adapt or die.
The discovery shocked and excited orchid researcher Claire Micheneau.
"Watching the footage for the first time, and realizing that we had filmed a truly surprising shift in the pollination of Angraecum, a genus that is mainly specialized for moth pollination, was thrilling," Micheneau said.
The orchids were of particular interest because they were relatively new arrivals to the island from Madagascar, and did not have Madagascan insects around to pollinate them.
"This was not on anyone's radar," said professor Mark Chase, keeper of the Jodrell Laboratory at Royal Botanic Gardens, Kew, in the U.K. and co-author of the report.
