. The common spiders of the United States. Spiders. 26 THE COMMON SPIDERS thoroughwort.

Whether spiders prefer flowers colored like themselves is an unsettled question ; at any rate, Misu- menas of all colors and both sexes have been found on white flowers. Occasionally individuals are found on flowers of exactly the same color as themselves ; for example, deep yellow J/. aleatoria on the wild indigo, Baptisia tinctoria, and the reddish J/, aspcrata on the flowers of sorrel, Rumcx acctosella. The adult fe- males of vatia and aleatoria are easily mistaken for each other. Both vary in color from white to deep yellow, and grow to a large size, but they can be dis- tinguished by the differ- larged four times, q^^q J^ the shapC of the 78, male enlarged four _ times. head. Aspcrata is perhaps the most common species. The female seldom grows as large as the others, and does not lose entirely the red markings of the abdomen and legs. The scattered stiff hairs also distinguish it from the others. The males of the different species are distinct enough one from the other, though they differ widely from the females. The shape of the head and the markings around the eyes are much the same in both sexes, and by these males and females of the same species may be recognized. f.
