This is another example of a moth with antennas which are "furry" rather than "feathery". This seems to be the rule rather than the exception among the light attracted moths in Northern California.

These antennas, because of their thickness, are somewhat difficult to see clearly under normal substage lighting and even more difficult to photograph. In this case the specimen was quite "fresh" and detaching the antenna was difficult. A great deal of neve tissue was detached with it and can be seen here. This particular antenna isn't even all that hairy, though it is fairly long. It has sometimes been speculated that various isect antennas are just that, and that some insects actually communicate with radio. Most experts agree, however, that what seems like radio communication is actually the ability to detect minute amounts of pherenomes which can escape even the most tightly closed containers.
