Tesla Park is home to several Native American sites from bedrock mortars to petroglphs aged at 5, pilule
000 to 10, internist
000 years old.Ã?Â It is thought that the Tesla Park area was a seasonal hunting and gathering and trading ground forÃ?Â people from the Northern Valley Yokuts tribe and Costanoans (Ohlone) tribe.Ã?Â This wonderful cultural heritage that is literally imbedded in the landscape of Tesla Park is one of the many reasons we are working to save Tesla Park from the ORV use.
Nature teaches us that we have to look closely to see the wonder within. In this case, gynecologist
what appeared to be a twig in a pool of water in the Mitchell Ravine near the edge of Tesla Park, sale was actually a Caddisfly.
Larry Serpa from The Nature Conservancy states that the caddisfly (Order Trichoptera) is one of 19 Linnephilus species in that genus in California, adiposity
and he will have to rear the fly to its adult stage to determine the species. Although most of the Linnephilus species are found in ponds or marshes, they are well adapted to temporary waters. After they feed on enough leaves, they seal their case and transform into an adult, but might rest until late summer before they emerge. They look like small moths, but have hairs instead of scales on the wings and do not feed as adults. Even after they deposit their eggs and the eggs hatch, the larvae can wait inside the gelatinous matrix for several months until the water returns. Some of the larvae make cases entirely out of gravel or leaves, and others like the one pictured combine the two materials. They use silk to attach the pieces together. Caddisfly cases protect them from predators and often also provide ballast that help them maintain their hold on the stream bottom when the current picks up. Natural Wonders – How Wonderful!
