War boatmen
Today, I observed the water boatmen in our small garden pond raft up in a
kind of star shape. I have never seen this behaviour before, and I wonder if anyone could explain it to me? Here is a photo. The actual insects are about one centimetre long. http://community.webshots.com/photo/...60022413uWvwBn -- Cheers Quilly For four good books to read look at... http://www.quilljar.btinternet.co.uk/covers.htm Buy three or four altogether and get economy postage. |

Thank-you for that. So pond skaters eh? They still look intruiging as a
raft. They held it for some minutes but when I phographed them they dispersed. I wonder if Glbert White has anything to say about this? Quilljar |

Here is a page of a guy who probably could answer your question better...scroll down the page to get his email. http://www.ebc.uu.se/zooeko/GoranA/GA1.html -- Lar It is said that the early bird gets the worm, but it is the second mouse that gets the cheese. |
