The crab spider Misumenoides formosipes is an ambush predator whose males search for relatively sedentary females within a heterogeneous habitat. Females are receptive to mating immediately after their adult molt and a male biased adult sex ratio together with precopulatory guarding places a premium on male ability to locate females quickly. It is unknown what cues males use to find females; we report here on male movements in association with floral cues. Males in field trials moved towards… 

Specificity of attraction to floral chemistry in Misumenoides formosipes crab spiders

Crab spider males' use of olfactory cues to locate R. hirta inflorescences should increase encounters with potential mates, given that females in the population are found on that substrate more predictably than on any other.

Movement, sex ratio, and population density in a dwarf male spider species, Misumenoides formosipes (Araneae: Thomisidae)

While extreme SSD may be associated with enhanced mobility of small males during searches for females, it is not precluded by extensive male agonistic encounters.

Host Plant Availability and Nest-Site Selection of the Social Spider Stegodyphus dumicola Pocock, 1898 (Eresidae)

The use of host plants and the role of host plant features in the social spider Stegodyphus dumicola in Namibia are investigated and it is found that nests were relatively more abundant on specific plant species, on which the spiders also survived better.

Studies involving potential chemical attractants from Rudbeckia hirta inflorescences

The long-chain hydrocarbon wax interacting with the volatile components could play a major role in attracting the male crab spiders to the R. hirta inflorescences.

Crab spiders (Thomisidae) attract insect flower‐visitors without UV signalling

1. Crab spiders (Thomisidae) indirectly affect insect flower‐visitor and flowering plant interactions by consuming and altering the behaviour of insects.

Many paths, one destination: mapping the movements of a kleptoparasitic spider on the host’s web

The results show that kleptoparasitic spider movement is spatially structured, with higher levels of speed at the peripheries and slower in the centre of the web, and a high level of variation in trajectory shapes between individuals.



Pre-copulatory guarding of penultimate females by male crab spiders, Misumenoides formosipes

L Laboratory experiments with an entelegyne species supported the prediction that males would cohabit with penultimate females longer than with either adult-virgin or once-mated females, and field distributions of males corroborated these results.

Pick-up lines: cues used by male crab spiders to find reproductive females

This work explored one of the potential mate-locating tactics of adult males, their linefollowing behavior, and found that pheromones seem unlikely to aid males searching for unmated adult females.

Contrasting patch choice behaviour by immature ambush predators, a spider (Misumena vatia) and an insect (Phymata americana)

The aim of the work reported here was to investigate how immatures, as compared with adults, select sites from which to ambush their prey.

Contrasting patch choosing by anthophilous ambush predators: vegetation and floral cues for decisions by a crab spider (Misumena vatia) and males and females of an ambush bug (Phymata americana)

Field-collected individuals of Misumena vatia and Phymata americana were compared experimentally as to the kind of vegetation and flower cues they use to choose a hunting site, by introducing them


Evidence is presented that T.planicepsmales use cues from females' draglines deposited on the outside of these rolled-up leaves when searching for females hidden from view inside when living in the cavities of New Zealand flax leaves.


It appears that M. asperatus is basing its foraging decisions at least in part on assessment of a parameter in its environment that may correlate with prey abundance, without directly assessing prey arrival rates.

Dragline-Following by Male Lycosid Spiders

Wolf spiders stalk or ambush their prey rather than build preycapture webs, and determination of the use of various appendages during following, analysis of cues involved in initiating and maintaining trail-following, and an interspecific comparison of trailfollowing behavior are investigated.

Exploitation of floral signals by crab spiders (Thomisus spectabilis, Thomisidae)

Olfactory signal seems to be the floral signal that bees use to identify high-quality flowers and that crab spiders exploit to encounter honeybees.

Chemical attraction of male crab spiders (Araneae, Thomisidae) and kleptoparasitic flies (Diptera, Milichiidae and Chloropidae)

The attraction to (E)-2-octenal wa s the original goal of the study was abandoned in greater, but not significantly so, than to (e)-2 1993 in favor of a full-time investigation of spidecenal.

Species recognition and species isolation in wandering spiders (Cupiennius spp.; Ctenidae)

SummaryOne of the roles ascribed to spider courtship is that of mate recognition and reproductive isolation. We describe behavioral mechanisms underlying these functions in three species of wandering
