No leaves

Litter release - Rio San Lorencito Upstream 4-5-2009 6-45-31 AM

No artificial leaves ever made it to the end of our 30-m release, where the seine was set for their capture.  This is an interesting find, since litter biomass is relatively low in the stream itself; where is it going? Are tadpoles, which do appear to be abundant, processing litter?

Another fly!

Tipulid 2007-08-17 1-01-29 PM

This was the desktop background of my lab computer for well over year, so folks have probably seen it.  It looked much better on my 19” LCD screen than it did on that computer, so I’d figure I’d post it. 

It turns out though, that’s it’s another fly, which I always assumed was a Tipulidae.  I’m not sure if they have painted wings though, and it’s much more fun to post it here than look it up on Wikipedia.

Los Tabanos

One family of flies that I do know are the Tabanidae (tabanos, sweet bees, deerflies).  Mike also got to know them while in San Ramon; consequently, los tabanos conocen la cuchilla de Mike, mae.

Although I was only bitten a couple of times, Mike, Erin and Kyle suffered regular, nasty, stinging bites after several minutes of annoyingly circling their heads.  The tabanos were quite common in San Ramon, but I only saw larva in the wetland at Palo Verde.
