Genome report: Genome sequence of tuliptree scale, Toumeyella liriodendri (Gmelin), an ornamental pest insect.

Scale insects are of interest both to basic researchers for their unique reproductive biology and to applied researchers for their pest status. In spite of this interest, there remain few genomic resources for this group of insects. To begin addressing this lack of data, we present the genome sequence of tuliptree scale, Toumeyella liriodendri (Gmelin) (Hemiptera: Coccomorpha: Coccidae).

An annotated and illustrated catalog of the primary type material of Hemiptera deposited in the Florida State Collection of Arthropods.

The Florida State Collection of Arthropods (FSCA) is one of the largest and most diverse insect collections in North America and the largest in the southeastern United States with over twelve million curated specimens and significant amounts of materials in bulk collections and other unprocessed samples. The order Hemiptera currently comprises approximately 95,000 species in three suborders. The FSCA houses type material in the auchenorrhynchan families Cicadidae, Cicadellidae, Cixiidae, Delphacidae, Derbidae, and Membracidae; the heteropteran families Coreidae, Corixidae, Curaliidae, Lygaeidae, Miridae, Pentatomidae, Reduviidae, Schizopteridae, Scutelleridae, and Tingidae; the sternorrhynchan families Aleyrodidae, Aphalaridae, Aphididae, Coccidae, Diaspididae, Matsucoccidae, Pseudococcidae, Phacopteronidae, and Triozidae.

Conspicuous stripes on prey capture attention and reduce attacks by foraging jumping spiders.

Many animals avoid predation using aposematic displays that pair toxic/dangerous defences with conspicuous achromatic warning patterns, such as high-contrast stripes. To understand how these prey defences work, we need to understand the decision-making of visual predators. Here we gave two species of jumping spiders ( and ) choice tests using live termites that had their back patterns manipulated using paper capes (solid white, solid black, striped).

Juvenile leg autotomy predicts adult male morph in a New Zealand harvestman with weapon polymorphism.

Intraspecific weapon polymorphisms that arise via conditional thresholds may be affected by juvenile experience such as predator encounters, yet this idea has rarely been tested. The New Zealand harvestman has three male morphs: majors (alphas and betas) are large-bodied with large chelicerae used in male-male contests, while minors (gammas) are small-bodied with small chelicerae and scramble to find mates. Individuals use leg autotomy to escape predators and there is no regeneration of the missing leg.

Sexually dimorphic dorsal coloration in a jumping spider: testing a potential case of sex-specific mimicry.

To avoid predation, many animals mimic behaviours and/or coloration of dangerous prey. Here we examine potential sex-specific mimicry in the jumping spider . Previous work proposed that males' conspicuous dorsal coloration paired with characteristic leg-waving (i.

Muscle mass drives cost in sexually selected arthropod weapons.

Sexually selected weapons often function as honest signals of fighting ability. If poor-quality individuals produce high-quality weapons, then receivers should focus on other, more reliable signals. Cost is one way to maintain signal integrity.

Specialists and generalists coexist within a population of spider-hunting mud dauber wasps.

Individual foraging specialization describes the phenomenon where conspecifics within a population of generalists exhibit differences in foraging behavior, each specializing on different prey types. Individual specialization is widespread in animals, yet is understudied in invertebrates, despite potential impacts to food web and population dynamics (Hymenoptera: Sphecidae) is an excellent system to examine individual specialization. Females of these mud dauber wasps capture and paralyze spiders which they store in mud nests to provision their offspring.

Frequent misdirected courtship in a natural community of colorful Habronattus jumping spiders.

Male courtship display is common in many animals; in some cases, males engage in courtship indiscriminately, spending significant time and energy courting heterospecifics with whom they have no chance of mating or producing viable offspring. Due to high costs and few if any benefits, we might expect mechanisms to evolve to reduce such misdirected courtship (or 'reproductive interference'). In Habronattus jumping spiders, males frequently court heterospecifics with whom they do not mate or hybridize; females are larger and are voracious predators, posing a severe risk to males who court indiscriminately.
