Nondestructive temperature and radiance measurements on night flying moths.

Measurements are given of the temperature and ir emission of three species of night-flying moths. A radiometric microscope was utilized to make nondestructive measurements of the vibrating moths and also to measure the ir reflectivity of the dull-colored wing scales of the moths. The possible utilization of coherent and incoherent ir signals in the communication systems of the insects is discussed.

A high frequency dielectric waveguide on the antennae of night-flying moths (Saturnidae).

When spines on the scape and pedicel of two species of saturnid moths were irradiated with visible coherent (6328 A) and incoherent radiation, the sensors responded to the light by sending a biphasic nerve impulse down the entire length of the central antennal nerve. The biphasic action potential apparently gates the antennae and prevents the moth from responding to environmental signals during daylight.
