Two species of fire ants, Solenopsis geminata (Fabricius) and Solenopsis invicta (Buren), pose important threats to sea turtles, attacking hatchlings both within the nest and as they emerge and head towards the ocean. We surveyed ants at permanent markers along a major sea turtle nesting beach at Sandy Point National Wildlife Refuge, Saint Croix, US Virgin Islands, where both S. geminata and S. invicta occur. Over the course of five surveys in 2006, 2010, 2014, 2018, and 2022, the percent of tuna baits with S. geminata or S. invicta present declined from 48% in 2006, to 30%, 16%, 2%, and 4% in the four subsequent surveys. The reasons for the decline in fire ants on this beach are uncertain, but it is likely a positive development for nesting sea turtles.

Here we review changes to the planthopper (Hemiptera: Fulgoroidea) fauna north of Mexico since the publication of “A review of the planthoppers (Hemiptera: Fulgoroidea) of the United States” (Bartlett et al. 2014). There are 12 species in 4 families added to the fauna and 50 changes in the generic assignment in 4 families. The most significant faunal addition is the spotted lanternfly (Lycorma delicatula (White)), with populations reported in 14 states and vagrants in 3 more. We review some nomenclatural and taxonomic issues and provide a list of anomalous records that may represent unreported or undescribed species that require further investigation. All told, these additions and changes (excluding anomalous records) give totals of 175 genera and 924 species in 13 families of planthoppers, a net addition of 1 family, 8 genera, and 10 species to the tally provided in 2014.

Carpocoris mediterraneus is a polyphagous vegetarian. Adult females of C. mediterraneus were collected in Aksu, Antalya, in June 2018. In this study, the morphological structures of female reproductive system of C. mediterraneus, which has not been studied before, was investigated under light and electron microscopies. The female reproductive system of C. mediterraneus was composed of a pair of ovaries, lateral oviducts, a common oviduct, accessory gland and spermatheca. Each ovary consisted of six telotrophic meroistic type ovarioles. Each ovariole consisted a terminal filament, germarium, vitellarium, and pedicel. In the germarium region, there was a trophic core, trophocytes, young oocytes and prefollicular cells. Vitellarium contained three oocytes at various stages of maturity (previtelogenesis, vitellogenesis, choriogenesis). The ovarioles were connected via pedicels to a pair of short lateral oviducts and subsequently to a common oviduct. The spermatheca of C. mediterraneus consisted a spermathecal bulb, a pumping region, the distal duct, dilation region, proximal duct and genital chamber. The spermathecal bulb was oval in shape and strongly chitinized. Its lumen typically contains a large number of spermatozoa.

Bees are indispensable living components of ecosystems because of the pollination services they offer. In this respect, it is important to determine the extent of host plant specialization by evaluating their pollen diet, information that can easily be gathered by analyzing the pollen content of their nests. Here we examined two Xylocopa (Copoxyla) iris (Christ, 1791) nests from different provinces in Turkey to identify the relationship between the surrounding vegetation and the possible pollinator or forager X. iris, a species for which there is limited available pollen preference data. We investigated the larval provisions and pollen content of these nests and compared pollen content with the pollen of the surrounding vegetation. In addition, we inspected the nest architecture and nesting biology and reviewed extant information about the distribution of this species in Turkey. Our investigation found that both nests were unbranched with 7-8 cells, each containing seven individuals at different stages of development. Pollen analysis revealed that plants of the families Fabaceae and Lamiaceae were most preferred by X. iris. These findings suggest that even though the nectar and pollen foraging behavior of this species is known to be polylectic, their larval diet choices might be much more specialized.

A new species from India, Conocephalus (Aniosptera) himalayicus Chandra, Kumar & Chand sp. nov.is described and illustrated. The new species is the fifth brachypterous species of subgenus Aniosptera Latreille, 1829 from India. A checklist of Indian species of Conocephalus Thunberg, 1815 is also provided.

The classification of North American species of Prionus (Prionus) Geoffroy, sensu lato, is reevaluated based on male antennal morphology, with three subgenera being recognized: P. (Prionus), consisting of P. aztecus Casey, P. californicus Motschulsky, P. evoluticornis Komiya & Nogueira, P. flohri Bates, P. heroicus Semenov, P. howdeni Chemsak, P. laticollis (Drury), P. lecontei Lameere, P. mexicanus Bates, P. pocularis Dalman, and P. poultoni Lameere; P. (Antennalia) Casey, revived status, consisting of P. fissicornis Haldeman; and P. (Neopolyarthron) Semenov, revived status. The species of P. (Neopolyarthron) are revised and consist of P. imbricornis (Linnaeus), P. debilis Casey, revived status, and P. cuneatus Casey, revived status, with the latter two species being removed from synonymy with P. imbricornis. Prionus robustus Casey, new synonymy, is transferred from synonymy with P. imbricornis to synonymy with P. cuneatus. Prionus fissicornis parviceps Casey, revised synonymy, is removed from synonymy with P. imbricornis and returned to synonymy with P. fissicornis. A lectotype is designated for Cerambyx imbricornis Linnaeus. Keys to North American subgenera of Prionus and to species of P. (Neopolyarthron) are provided. The species of P. (Neopolyarthron) are redescribed, diagnosed, and illustrated, with the female of P. debilis being illustrated for the first time. A county-level distribution map is provided for each species of P. (Neopolyarthron) along with a detailed discussion of distribution, host records, habitat, and conservation status. Prionus imbricornis is associated with forested habitats, P. debilis is associated with tallgrass prairies, and P. cuneatus is associated with prairies and other grasslands. Prionus fissicornis is diagnosed from species of P. (Neopolyarthron), and the type specimens of P. (Antennalia) fissicornis parviceps Casey, P. (Antennalia) fissicornis transversus Casey, and P. (Antennalia) thoracicus Casey are reviewed and illustrated. The date of publication for P. fissicornis is corrected from 1846 to 1847.

Isophya nervosa (Orthoptera, Tettigoniidae) is especially localized in Ankara, Çankırı, Eskişehir, Turkey. Although there are many systematic and taxonomic studies on I. nervosa, there is no study on the morphology and ultrastructure of the digestive. For this purpose, the hindgut of Isophya nervosa (Orthoptera, Tettigoniidae) was investigated by using light and electron microscopes in detail. The outer surface of the hindgut is covered with connective tissue and muscle layer containing abundant trachea. The lumen of all parts of hindgut (ileum, colon, rectum) is surrounded by a cuticular intima that lines single layer cuboidal epithelium throughout the entire length of the hindgut. The monolayer cuboidal epithelium in the colon, which is the middle part of the hindgut, has deep folds. The rectum is a wide elongated sac and has six rectal pads.

In this study, zoogeographic evaluations of the Turkish Cantharidae family were performed. In this context, the faunistic similarities between the geographical regions of Turkey, Turkey- neighbor countries, and the Turkey-Subregions of the Palaearctic region were compared. According to current literature, the Turkish fauna of the Cantharidae is composed of two subfamilies, 15 genera, and 254 species (of which 167 are endemic species). The Mediterranean region has the most species (106 species) and the most endemic species (74 species). The highest similarity is found between the Central Anatolian and Aegean regions (60.2%). Cantharis livida Linnaeus, 1758 is distributed in all Turkey geographical regions. The Turkish cantharid fauna is more similar to that of Iran than other neighboring countries when comparing subregions of the Palaearctic region. The Cantharidae fauna of Turkey showed the most similarity to the fauna of the Middle East with a rate of 55.2%.
