Fall Webworm Silk
This is an image of the silk from Hyphantria cunea, the Fall
Web Worm. The
caterpillars of this moth form tents in the branches of trees in the autumn of the year.
The silk
forming the tent of Hyphantia cunea varies wildly in diameter. As the caterpillar grows
it forms a
thicker silk.
Transmitted Crossed Circular Polarized Light
Definition/Function:
Hyphantia cunea is a nearly all white moth that is wide spread in North America, Asia, and
Europe. Transmitted crossed circular polarized light eliminates extinction positions and
provides the maximum interference for the particles relative to their position on the slide.
There is no need to rotate the stage to enhance the interference colors.
