Table 2. Species included in PGLS analyses by spider family.

Twenty-two species across thirteen spider families were used in the PGLS analyses. The scoring for the five independent variables, from Foraging Strategy to Maximum Number of Instars is reported here. ‘Strategy’ delineates web (0) or no web usage (1). ‘Specific’ refers to the type of prey pursuit (1–3) or web (4–5) used by each species. ‘Silk’ quantifies the main type of silk used by each species from aciniform (1) to viscous (4). ‘Type’ is a numerical designation for the variety of silk spigot types each species possesses from the ‘standard 7’ (1) to standard 7 + paracribellar + cribellum + pseudoflagelliform (4). Finally, ‘Instar’ refers to the maximum number of instars reported for adult females of each species.
