</P><P>
The finding helps explain why many flowers waft in the breeze, and reveals a hitherto unknown trick used to attract pollinators.
</P><P>
Scientists made the discovery while studying common wildflowers known as sea campion on the Welsh coast. 
</P><P>
Mobile flowers are visited more often by insects and also produce more seeds, they report in the Journal of Evolutionary Biology.
</P><P>
Moving flowers also attract a wider variety of insect species than more static blooms. 
</P><P>
For years, biologists have known that flowers use striking colours, fragrances, elaborately shaped petals and nectar to attract pollinating insects such as bees and flies.
</P><P>
Yet no-one had ever seriously considered whether wafting in the wind acted as a similar signal.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.bbc.co.uk/1/hi/sci/tech/7388689.stm"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/news.bbc.co.uk/img/4F821CE3-8AEA-4CD4-B6D9-09EA83A807E5" alt="Bumblebee on flower.
