Hemipteran defensive odors trigger predictable color biases in jumping spider predators
<p>Multimodal warning displays often pair one signal modality (odor) with a second modality (color) to avoid predation. Experiments with bird predators suggest these signal components interact synergistically, with aversive odors triggering otherwise hidden aversions to particular prey colors. In a recent study, this phenomenon was found in a jumping spider (<em>Habronattus trimaculatus</em>), with the defensive odor from a coreid bug (<em>Acanthocephala femorata</em>) triggering an aversion to red. Here, we explore how generalizable this phenomenon is by giving <em>H. trimaculatus</em> the choice between red or black prey in the presence or absence of defensive odors secreted from (1) eastern leaf-footed bugs (<em>Leptoglossus phyllopus</em>, Hemiptera), (2) grass stinkbugs (<em>Mormidea pama</em>, Hemiptera), (3) Asian ladybird beetles (<em>Harmonia axyridis</em>, Coleoptera), and (4) eastern lubber grasshoppers (<em>Romalea microptera</em>, Orthoptera). As expected, in the presence of the hemipteran odors, spiders were less likely to attack red prey (compared to no odor). Unexpectedly, the beetle and grasshopper odors did not bias spiders away from red. Our results with the hemipteran odors were unique to red; follow-up experiments indicated that these odors did not affect biases for/against green prey. We discuss our findings in the context of generalized predator foraging behavior and the functions of multimodal warning displays. </p>

Data from: The role of male coloration and ornamentation in potential alternative mating strategies of the dimorphic jumping spider, Maevia inclemens
Polymorphism can arise across taxa due to various selection pressures and potentially lead to alternative mating or antipredator strategies. For male jumping spiders, sexual selection and predation risk are often intertwined when courting cannibalistic females and may be a driving factor in the polymorphism of the jumping spider, Maevia inclemens. The dimorphic males of M. inclemens differ dramatically in their complex courtship behavior and display traits that may function as alternative mating strategies to reduce female aggression and maximize mating success. We hypothesized that males of the "tufted" morph honestly communicate condition or body size to females with three conspicuous tufts of setae on their head and males of the "striped" morph reduce female aggression with coloration commonly found in aposematic animals (here, yellow-orange pedipalps and striped legs). We examined correlations between tuft length and symmetry and metrics of body size and condition in field-collected spiders and conducted prey color choice tests (with live color-manipulated prey) to determine if yellow-orange and striped prey are avoided. Tuft length was variable and correlated with male size (but not condition). All prey color types were attacked at equal rates, but spiders oriented to striped prey more often, suggesting that male stripes may attract female attention without increasing predation. This study provides insight into the potential functions of the different courtship and visual displays of M. inclemens males. Using jumping spiders to study polymorphism can provide new insight into how multiple morphs can evolve, as males use mating strategies not only to impress females but also avoid getting eaten by their potential mates.

Data from: Conspicuous stripes on prey capture attention and reduce attacks by foraging jumping spiders
<p class="MsoNormal"><span>Many animals avoid predation using aposematic displays that pair toxic/dangerous defenses with conspicuous achromatic warning patterns, such as high-contrast stripes. To understand how these prey defenses work, we need to understand the decision-making of visual predators. Here we gave two species of jumping spiders (</span><em>Phidippus regius</em><span><em><span> </span></em>and </span><em>Habronattus trimaculatus</em><span>) choice tests using live termites that had their back patterns manipulated using paper capes (solid white, solid black, striped). For </span><em>P. regius</em><span><em><span>,</span></em> black and striped termites were quicker to capture attention. Yet despite this increased attention, striped termites were attacked at lower rates than either white or black. This suggests that the termite's contrast with the background elicits attention, but the internal striped body patterning reduces attacks. Results from tests with </span><em>H. trimaculatus</em><span> were qualitatively similar but did not meet the threshold for statistical significance. Additional exploratory analyses suggest th</span>at attention to and aversion to stripes is at least partially innate and provide further insight into how decision-making played out during trials. Because of their rich diversity (over 6500 species) that includes variation in natural history, toxin susceptibility, degree of color vision, and dietary specialization, jumping spiders are well-suited to test broad generalizations about how and why aposematic displays work. </p>
Females pay little attention to variation in male display traits in a jumping spider with dimorphic males
<p><span>Dimorphic male alternative reproductive strategies typically involve divergent suites of morphological and behavioral traits to maximize reproductive success. Most instances of these strategies typically follow similar patterns of a larger, territorial or aggressive male morph and a smaller, satellite male morph. The genetically determined male morphs of the jumping spider, <em>Maevia</em> <em>inclemens</em>, have evolved dramatically different secondary sexual traits and courtship behavior, but do not seem to fit the classic mold of male alternative reproductive strategies. In the past several decades, advances have been made to better understand the different reproductive strategies between the morphs and how females (or predators) perceive them differently. However, the specific information content and function of their dimorphic morphological traits, and whether female aggression is an important factor in their evolution, is still not clearly understood. We tested two hypotheses for alternative mating strategies in <em>M. inclemens</em>. Tufted males have three tufts of setae above their eyes that may signal their mate quality. Striped males have contrasting black-and-white striped legs that may function as an aggression deterrent. We manipulated tuft length and the presence/absence of leg stripes and paired a single male with an unmated female in no-choice mating behavior experiments to quantify mating success, female receptivity, female aggression, and reproductive output. We found little support for our focal hypotheses. However, our models suggested that male body condition is more likely to influence mating interactions than variation in the target traits we manipulated. Our robust negative results allow us to critically revise our hypotheses to better understand the unique and perplexing male dimorphism of <em>M. inclemens</em> that deviates from current theory.</span></p>
Revalidation of the jumping spider genus Cheliceroides Żabka, 1985 based on molecular and morphological data (Araneae, Salticidae)
<p>The monotypic genus <em>Cheliceroides</em> Żabka, 1985 is revalidated based on both molecular sequence data (ultra-conserved elements and protein-coding genes of mitochondrial genomes) and morphological evidence. Results of molecular phylogenetic analyses show that <em>Cheliceroides</em> is not closely related to <em>Colopsus</em> Simon, 1902, not even in the same tribe, and comparative morphological study also demonstrates significant differences in the genital structures (e.g., the shape of embolus, with or without a pocket on the epigynum) of the two genera. Therefore, here we remove <em>Cheliceroides</em> from the synonymy of <em>Colopsus</em>, and its generic status is revalidated.</p>
