Announcements

Happy Holidays...
Thank you, volunteers, for all of your hard work this year.  We wish  
you the warmest and happiest holiday season.  See you in 2010!

StreamWatch Facebook page...
Short on time but want to help? Here’s a quick and easy way for  
Facebook users to raise awareness about Rivanna streams and rivers:
1) Become a fan of StreamWatch’s new Facebook page. Just Google  
“StreamWatch Facebook”, open the page, and click the “become a fan”  
button near the top of the page.
2) THIS IS THE MOST IMPORTANT STEP! Recommend the page to your  
Facebook friends who live in or care about the Rivanna basin. The  
purpose of the page is to catch the attention of people who are not  
currently tuned in.
3) Read our 70-word daily blogette for interesting, valuable, and  
sometimes entertaining information about the Rivanna, stream ecology,  
and water. A new blogette will post to your wall each weekday. At  
under one minute, we hope this read will be a painless (pleasant?!)  
way to expand knowledge!

December Bug Blog...
Go to the Bug Blog: http://streamwatch.org/bug-blog/the-invasive-virile-crayfish 
  to read about this month's bug, the invasive virile crayfish.  Keep  
an eye on the website for a new bug each month.

Bob's Bug Facts...
(brought to you by Bob Henricks)

Large Winter stoneflies appear in our samples from mid-October through  
the mid-March.  Since we do not sample a lot in the winter, most  
volunteers rarely see them.  There are only five genera of Large  
Winters in our part of the country, and most of the Large Winters we  
see belong to one of two genera: Taeniopteryx or Strophopteryx.  Both  
have distinguishing features.  Taeniopteryx (http://www.troutnut.com/specimen/350 
) have small finger-like gills that stick out from the base of each  
leg. Strophopteryx (http://bugguide.net/node/view/264076/bgimage) have  
a triangular plate at the end of the underside of the abdomen.   
Neither of these features is visible to the naked eye. When mature,  
they also differ by color. Taeniopteryx (http://bugguide.net/node/view/254456 
) tend to be dark brown with a cream stripe down the middle.  
Strophopteryx (http://bugguide.net/node/view/264075/bgimage) tend to  
be brownish yellow with mottled wingpads and head.
