Hyalella Azteca
I have recently been inspired by a small creature called the Hyalella Azteca,
a little-known crustacean that lives in the sediment of streams and shallow
waters throughout the world. Recently, studies have found high levels
of toxicity at very low concentrations to the hyalella azteca due to the
increasing use of a new group of pesticides called pyrethroids found in urban
stormwater. I have created artwork in batik to highlight the connection
between pesticides and the destruction of this very cool creature.
Hyalella Azteca are an important food source for trout and salmon.
In fact, there can be over 10,000 hyalella living within a square yard, darting
about underneath rocks and plants to hide from predators.
Hyalella Azteca can grow up to ¼ inch long, here shown in size related
to a penny. They are scavengers that eat microscopic plants, animals, and
debris found at the bottom of streams. If you look closely, you will probably
be able to see them in your local stream.
Ants! Unfortunately, pesticides used to control ants are highly toxic to
the hyalella. Over 80,000 pounds of pyrethroid are used every year in the
San Francisco Bay area to control ants, much of it sprayed outside on foundations
and on lawns. When it rains, stormwater carries the pesticides into streams.
Pyrethroids can be lethal to the tiny hyalella at concentrations as low as
several parts per billion (less than a teaspoon in an Olympic size pool).
Hyalella Azteca, though small and generally overlooked, are a vital part
of most aquatic ecosystems. Proper use of pesticides and proper disposal
of all waste to prevent stormwater pollution can help save these creatures
and the trout, salmon and other fish that depend on them.
Other recent work has been taking a new
direction, incorporating figurative works with a 3-dimensional structural
component. Mostly just fun. This is part of a series of 4 called
"pass the ball"
