Distribution of Metazygia carolinalis (Archer), M. wittfeldae (McCool<) and M. zilloides (Banks). feldae becomes active after dark, tearing down remnants of the old web and making new radii, scaffolding and viscid threads. The old web is usuallv left nntil a new one is built, which may not be every night. Threads coated with cornstarch (dusted by photographers the previous night) are hauled in, two sections at a time, balled up, and thrown horizontally away from the web, with some force, at the rate of a ball every minute or two. Silk not dusted is probably eaten. During the day the spider remains in a crevice; at night it hangs in the center of the web. The light from a flash- light may cause the spider to move away. The webs observed at the Archbold Bio- logical Station, Lake Placid, Florida were loose with few frame threads and 10 to 18 radii. The number of viscid threads in several webs was 18, 16, 22, 25, 15 below the hub and 11, 3, 3, 17, 10 above the hub. The webs had solid hubs (Plate 6) and horizontal diameters ranging from 10 to 27 cm. \\xbs, as many as five next to each other in a suitable comer, were vertical be- tween railings of a ramp 35 cm above the ground; at m above the level of the ramp, imder the ceiling, the webs were al- most horizontal. The spiders avoided the area near a light fixtine, but used areas some distance away, where they hai"vested insects attracted to the light. Species. There are three species north of Mexico; most other species are tropical American (Map 3); none is known outside of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
