“…Alternatively C. algerina may have captured web builders while in or at the edges of their webs and then moved away from the webs to feed. In typical encounters with web-building spiders in the laboratory, the behaviour of the Azerbaijan C. algerina resembled that of all species and populations of Cyrba that have been studied (Jackson & Hallas 1986b;Jackson 1990a;Jackson 2002). Cyrba moved slowly onto the edge of web, but placed only its forelegs on the silk.…”

The life cycle and natural diet of Cyrba algerina (Lucas) in the Apsheron Peninsula (Azerbaijan) was determined by sampling at frequent intervals throughout the year. Early-instar juveniles emerged in late July, grew to about half of adult size by winter, over-wintered and then, in the spring of the following year, grew to adult size and reached maturity. The primary mating season was in May, after which the number of adults in the population declined sharply. Ten arthropod orders were represented in the prey records from nature. Six of these were insects and four were arachnids. Spiders (order Araneae) were the dominant prey, accounting for 56% of the records. Half of these spiders were from one family, Oecobiidae. In laboratory prey-choice tests, C. algerina selected spiders in preference to insects and selected oecobiids in preference to other spiders. Video taping under infrared light confirmed that the Azerbaijan C. algerina captures prey in complete darkness.

“…Spiders from at least five different families routinely invade the webs of other spiders and lure them as prey with vibratory signals (e.g. Pholcus 'cellar' or 'daddy long-leg' spiders [18]; salticid 'jumping' spiders from the genera Portia, Brettus, Cyrba and Gelotia [19,20]). Several jumping spiders have been reported to use trial and error to derive effective signals [7,19 -23].…”

Assassin bugs (Stenolemus bituberus) hunt web-building spiders by invading the web and plucking the silk to generate vibrations that lure the resident spider into striking range. To test whether vibrations generated by bugs aggressively mimic the vibrations generated by insect prey, we compared the responses of spiders to bugs with how they responded to prey, courting male spiders and leaves falling into the web. We also analysed the associated vibrations. Similar spider orientation and approach behaviours were observed in response to vibrations from bugs and prey, whereas different behaviours were observed in response to vibrations from male spiders and leaves. Peak frequency and duration of vibrations generated by bugs were similar to those generated by prey and courting males. Further, vibrations from bugs had a temporal structure and amplitude that were similar to vibrations generated by leg and body movements of prey and distinctly different to vibrations from courting males or leaves, or prey beating their wings. To be an effective predator, bugs do not need to mimic the full range of prey vibrations. Instead bugs are general mimics of a subset of prey vibrations that fall within the range of vibrations classified by spiders as 'prey'.

“…Salticids (jumping spiders) are the largest family of spiders comprising close to 6600 species (c. 12% of all described spiders) classified in 674 genera distributed globally (World Spider Catalog, 2023). They are easily recognizable by their large anterior median eyes, which likely contribute to their documented ability to learn and solve problems (Jackson, 2002). A great diversity of biological features has been documented for jumping spiders, including courtship, foraging behaviours, extreme sexual dimorphism and aggressive mimicry (reviewed in Richman & Jackson, 1992).…”

Advances in the reconstruction of the spider tree of life: A roadmap for spider systematics and comparative studies

In the last decade and a half, advances in genetic sequencing technologies have revolutionized systematics, transforming the field from studying morphological characters or a few genetic markers, to genomic datasets in the phylogenomic era. A plethora of molecular phylogenetic studies on many taxonomic groups have come about, converging on, or refuting prevailing morphology or legacy‐marker‐based hypotheses about evolutionary affinities. Spider systematics has been no exception to this transformation and the inter‐relationships of several groups have now been studied using genomic data. About 51 500 extant spider species have been described, all with a conservative body plan, but innumerable morphological and behavioural peculiarities. Inferring the spider tree of life using morphological data has been a challenging task. Molecular data have corroborated many hypotheses of higher‐level relationships, but also resulted in new groups that refute previous hypotheses. In this review, we discuss recent advances in the reconstruction of the spider tree of life and highlight areas where additional effort is needed with potential solutions. We base this review on the most comprehensive spider phylogeny to date, representing 131 of the 132 spider families. To achieve this sampling, we combined six Sanger‐based markers with newly generated and publicly available genome‐scale datasets. We find that some inferred relationships between major lineages of spiders (such as Austrochiloidea, Palpimanoidea and Synspermiata) are robust across different classes of data. However, several new hypotheses have emerged with different classes of molecular data. We identify and discuss the robust and controversial hypotheses and compile this blueprint to design future studies targeting systematic revisions of these problematic groups. We offer an evolutionary framework to explore comparative questions such as evolution of venoms, silk, webs, morphological traits and reproductive strategies.
