To quickly assess the difficulty of the text, read a short excerpt:
In some species there are striking differences between the colors and mark- ings of the very young spider and those which it attains after one or two changes of skin. Epeira diademata and Zilla x-notata, two of the commonest English spiders, are conspicuous examples of this. 2 According to Peckham, the young spiders often differ from adults, and in many species when the sexes differ when adult, the male being brighter, they are alike until they reach maturity, when the male, along, ^ with his s...exual development, acquires his brilliant color. Again, soon after hatching, young spiders, probably at the third or fourth moult, begin to show color more decidedly, and the colors are dis- tributed in the patterns characteristic of the species, and as the spiders continue to advance in age and make their successive moults, other and more marked changes maybe noted. 3 The truth appears to be 'that there are differences among species in the degrees of resemblance between imma- ture and adult forms, but that generally the likeness strengthens from the time of hatching onward to maturity.
