American Arachnological Society Behavioral Flexibility in Orb Web Construction: Effects of Supplies in Different Silk Glands and Spider Size and Weight Author(s):

Comparisons of webs spun in the field when both sticky and non-sticky silk supplies were complete, when both were recently depleted, and when only non-sticky supplies were depleted show that Leucauge mariana and Micrathena sexspinosa vary design features of their orbs such as numbers of radii and sticky spiral loops, web area and proportion covered with sticky spiral, sticky spiral symmetry, and spaces between sticky spiral loops in response to changes in the amounts of both sticky and non-sticky silk that they have available. Spider size, spider weight and possibly website also influence L. mariana web designs.
