We've found that the cursorial spider prefers the cotton fleahopper, which is smaller than the cotton plant bug.
Cursorial spiders that wander in vegetation with EFNs are likely to encounter nectar, which they have the potential to detect with "gustatory" hairs on their tarsi (Barth 2002).
Members of the consobrinus exerge are relatively small, their dorsolateral light stripes tend to be bright, dorsal spotting is usually present in both sexes except in the bleached, arenicolous taxa, and all are terrestrially cursorial.
However, whether movement of spiders into agroecosystems is via ballooning compared to cursorial activity requires further study.
Most lynx spiders (Oxyopidae Thorell 1870) are typical cursorial hunters, which possess relatively keen eyesight and do not use silk for prey capture (Kovoor & Munoz-Cuevas 1997).
As is typical of cursorial spiders (Nentwig 1986; Nyffeler et al.
The large number of non-web spinning, cursorial Lycosidae (Table 1; 38% of all species, excluding nomina dubia) with undescribed mermithids, suggests that a direct life cycle may be involved in some instances.
For spiders in general, cursorial dispersal and ballooning induce different colonization and extinction patterns, dependent on the species' mobility, its niche breadth and its propensity for aerial dispersal (Bonte et al.
For example, one entire clade, or lineage, of 16 species (the "spiny leg" clade), has "lost" web building behavior, with the concomitant development of long spines along the legs and adoption of a vagile, cursorial, predatory strategy.
In cursorial spiders, elongated segments of legs, in particular the first pair, have also been reported in combination with ornamentations in species with visual courtship display (Kronestedt 1990; Hebets & Uetz 2000).
Longer legs may help cursorial males in their search for females (Montgomery 1910), they may provide males with a wide sensory radius and keep them relatively safe from female aggression (Elgar et al.
