Prey and predatory behavior of two zodariid species (Araneae, Zodariidae)
In this study, we investigated whether two plesiomorphic zodariid species, Lachesana insensibilis Jocque 1991 and Pax islamita (Simon 1873), both from Israel, possess adaptations for myrmecophagy similar to those of apomorphic zodariid gener...

Trophic strategy of ant-eating Mexcala elegans (Araneae: Salticidae): Looking for evidence of evolution of prey-specialization
We investigated the trophic strategy of Mexcala elegans Peckham & Peckham 1903, an ant-eating salticid spider from South Africa, in order to gain baseline information concerning the evolution of prey specialization......

Phenotypic integration in a series of trophic traits: tracing the evolution of myrmecophagy in spiders (Araneae)
Several hypotheses have been put forward to explain the evolution of prey specificity (stenophagy). Yet little light has so far been shed on the process of evolution of stenophagy in carnivorous predators....

Is there ontogenetic shift in the capture traits of a prey-specialized ant-eating spider?
ere, we focused on the ant-eating Zodarion rubidum, a spider strictly specialized on ants. It uses potent venom to immobilize prey. We tested whether there is a change during the ontogenesis of the spider species in traits related to capture efficien...

Innate prey preference overridden by familiarisation with detrimental prey in a specialised myrmecophagous predator
Prey-specialised spiders often do not have brood care and may not deposit eggs in the proximity of the preferred prey. Thus, naive spiderlings are left to their own to find their focal prey. Our aim was to reveal whether the choice of a specific prey...

Trophic specialisation in a predatory group: the case of prey-specialised spiders (Araneae)
Predators appear to be less frequently specialised (i.e. adapted to restricted diet) on their prey than herbivores, parasites or parasitoids. Here, we critically evaluate contemporary evolutionary hypotheses that might be used to explain the evolutio...

Evolution of ant-eating specialization in the basal lineage of Zodariidae (Araneae): the trophic ecology of South American Leprolochus birabeni Mello-Leitao
Most spiders are euryphagous predators. However, there are also a few species with a stenophagous diet, foraging on only a single prey taxon. This strategy could have resulted from ecological opportunity or from evolutionary specialization, which is ...
