Bee creates nest out of flower petals

NPR reports on the discovery of a bee that builds tiny, multi-coloured nests out of flower petals. The rare solitary bee Osmia avoseta creates the cocoons out of a mixture of mud, flower petals and nectar. Each case holds a single egg.


The discovery by a group of scientists in Turkey co-incided with that of another team in Iran; the two groups published their findings together in the American Museum Novitae. More pictures and info on

Sometimes a picture can tell you a lot about evolution. This particular picture has a story to tell about how two species--in this case a fly and an orchid--can influence each other's evolution. But the story it tells may not be the one you think. Coevolution, as this process is now called, was one…
Many plants depend so heavily on visits from bees that they go to great lengths to attract them, using brightly coloured flowers baited with sweet nectar. But some of their tricks are much subtler and are designed not to attract six-legged visitors, but to make their stay more convenient. The…
This is the fourth of eight posts on evolutionary research to celebrate Darwin's bicentennial. Charles Darwin was a visionary in more ways than one. In 1862, Darwin was studying a Malagasy orchid called Angraecum sesquipedale, whose nectar stores lie inaccessibly at the bottom of a 30cm long…
To sequence the human genome, scientists established a network of laboratories, equipped with robots that could analyze DNA day and night. Once they began to finish up the human genome a few years ago, they began to wonder what species to sequence next. With millions of species to choose from, they…

Nicely done, certainly more colorful than caddis fly larva tubes.

Whaaaat? Rob is wrong? Caddis fly larva tubes are more colorful? Is the only materials available for these bees always pedals? Your cryptic comment don't make no good sense. What am I missing?

All the links on this page give me a message like "Error establishing a database connection" so I didn't see that site before posting. However when I read the URL without actual seeing the page it became crystal clear.
"Me thinkith me" found a great blog.

Ah, that's not right, thanks for letting me know. Hopefully will get things back online soon.

We discovered the Osmia avoseta building these petal homes under out garden umbrella. Never seen anything like it. It had been raining for a few days so we didn't have the umbrella up, when we opened it two petal nests fell out. The bee is now trying to build more nests. Not sure what to do as the umbrella will be put away soon. I had to google to find what it was.
