Staphylinidae Latreille, 1802, commonly known as rove beetles, represent one of the largest and most diverse families within the order Coleoptera Linnaeus, 1758. These beetles exhibit a remarkable array of ecological adaptations and behaviors, with their success partly attributed to their ability to communicate using pheromones. Pheromones in rove beetles serve various functions, including territorial marking, defense, aggregation, and mate attraction. These chemicals are released by glands located on the abdomen. Research has identified several types of pheromones in Staphylinidae, including sex pheromones and defensive compounds. Sex pheromones, typically produced by females, attract males for mating, while defensive compounds act as alarm signals, alerting nearby individuals to potential threats and coordinating collective defensive behaviors. Gas-liquid chromatography is commonly used to extract and isolate these pheromones. The potential of pheromones in the Staphylinidae family is significant for pest control and other commercial applications. Continued research into pheromone composition, synthesis, and function in these beetles provides valuable insights into their biology and offers practical benefits. As research progresses, these beetles could be utilized for a variety of beneficial purposes.

Physocnemum andreae (Coleoptera: Cerambycidae) (Haldeman, 1847), the cypress bark borer, is a rarely collected cerambycid beetle associated with bald cypress (Cupressaceae: Taxodium distichum (L.) Rich). Despite the widespread distribution and abundance of the host plant in the eastern United States, published records of P. andreae are sparse. To better understand the distribution of this species we searched for records in the literature, online database sites, citizen science platforms (iNaturalist and BugGuide,) and we contacted researchers and curators at major collections in the eastern United States asking them to examine their holdings for possible P. andreae specimens and to share collection data if present. We give collection data for records, add eight new state records, provide a habitus image for P. andreae, present an updated distribution map, discuss possible hosts, and discuss why there is a lack of published records.

Although the use of insects in solving murders in Turkey is still in its infancy compared to other developed countries, it is seen that insects are used in solving some murders. İstanbul is the largest city in terms of population in Turkey. In parallel with this, İstanbul is one of the cities where the most murders are committed. For this reason, in this study, it was aimed to reveal the forensic entomologically important insect fauna and to determine the insect succession of İstanbul, where the most murder cases are seen. The study was carried out at Marmara University Başıbüyük Campus in Maltepe district on the Asian side of İstanbul, using four rabbit carcasses representing each season. At the end of the study, 33 species belonging to four insect orders were identified. Of these, 11 belonged to Diptera, 20 to Coleoptera, one to Hymenoptera and one to Hemiptera. In this study, insect succession was also examined and the succession of insect species coming to the carcass was revealed. This study is the first detailed study conducted in İstanbul province in terms of the detection of insect species which are important for forensic entomology.

We present a checklist of 26 ant species found in Mauritania, based on published, unpublished, and new records. There are published records of only 15 ant species from Mauritania, almost all based on specimens collected during a 1908 expedition. In September 2022, we surveyed ants for three days in the Dakhlet Nouadhibou Region of northwestern Mauritania. We collected 13 ant species, including 11 with no previously published records from Mauritania: Cardiocondyla emeryi Forel, 1881, Cardiocondyla mauritanica Forel, 1890, Cardiocondyla nigra Forel, 1905, Hypoponera punctatissima (Roger, 1859), Lepisiota canescens (Emery, 1897), Messor foreli Santschi, 1923, Monomorium salomonis (Linnaeus, 1758), Paratrechina longicornis (Latreille, 1802), Pheidole indica Mayr, 1879, Pheidole megacephala (Fabricius, 1793), and Tetraponera ambigua (Emery, 1895). Our checklist remains woefully incomplete; e.g., neighboring countries of Morocco and Algeria each have more than 200 known ant species.

Hymenoptera have been surveyed from many regions of Türkiye, but far western provinces are underexplored. This study targets the identify species in wasp group belonging to Hymenoptera order collected from in Çanakkale province. Sweep net samples were examined from five localities emphasizing 24 habitats. This effort resulted in 42 specimens, spanning 24 species. Of these, 20 were new records for the Çanakkale Province, as follows: Astata kashmirensis Nurse, 1909; A. minor Kohl, 1885; Ammatomus asiaticus (Radoszkowski 1886); Ammophila hungarica Mocsáry, 1883; Cerceris eucharis Schletterer, 1887; C. sabulosa (Panzer, 1799); Eumenes dubius de Saussure, 1852; E. mediterraneus Kriechbaumer, 1879; Gorytes albidulus (Lepeletier, 1832); Gymnomerus laevipes (Shuckard, 1837); Harpactus laevis (Latreille, 1792); Leptochilus (Lionotulus) hermon Gusenleitner 1971; Odynerus melanocephalus armeniacus (Morawitz, 1885); Podalonia hirsuta mervensis (Radoszkowski, 1887); Polistes nimpha (Christ, 1791); Sceliphron madraspatanum (Fabricius, 1781); Tachysphex brullii (F.Smith, 1856); Trypoxylon figulus (Linnaeus, 1758); Vespa crabro Linnaeus, 1758; V. orientalis Linnaeus, 1761. One was also a new record for Türkiye: Ammatomus asiaticus (Radoszkowski 1886). This study was carried out to reveal the wasp diversity of the region.

Ochetellus glaber clarithorax is an ant native to humid subtropical areas of Queensland and New South Wales in eastern Australia. In 1979, a non-native population of O. glaber was reported from Winter Park, in Orange County, Florida. Since then, there have been several other O. glaber site records in Florida, all from Orange County, except one from neighboring Lake County. In 2019–2020, I collected this species, which I identify as Ochetellus glaber clarithorax, at 17 sites in east-central Florida, ranging in latitude from 28.3°N–29.8°N, all from sites with a humid subtropical climate. These include the first site records of this species from Brevard, Flagler, Osceola, St Johns, Seminole, and Volusia counties. My new Florida records of O. glaber clarithorax suggest that populations are expanding northward and eastward, but not southward. Ochetellus glaber clarithorax is one of the few non-native ants in Florida not known from the more southern, tropical parts of the state. Ochetellus glaber clarithorax may only be able to successfully invade humid subtropical areas.

In this study 34 species of Cerambycinae have been identified. In addition to determining the fauna of the Aegean Region, the sampling altitude, months and habitats of the species with number of individuals, were recorded. In addition, the morphological parts of the male and female genitalia of 16 species have been described and drawn for the first time. The existing faunal structure of the Aegean Region has been attempted to be exposed through the study, and new locality records from the region have contributed to the biodiversity of Türkiye.

The present paper describes some of the more frequently occurring crickets of the subfamily Gryllinae, collected from different provinces of India, with additional characterization of their morphological and genitalic traits. The description has been supported with suitable diagrams, plates, and modified keys to these species.

We observed aggressive worker biting behavior (AWBB) in Nasutitermes nigriceps in which the worker caste rapidly, consistently, and persistently bit into, and clung tightly to human flesh causing a mild sting-like sensation. We used a forearm exposure test to evaluate how widespread this behavior was among termites in Mexico and the western United States. Among the termites tested, we determined that the behavior is limited to only the Nasutitermes nigriceps complex. We hypothesize that this presumably mammal–directed defensive behavior by the worker caste evolved in this group because their large arboreal nests are uniquely exposed to increased predation pressure from specialized arboreal mammals such as the tamanduas. Altruistic sacrifice for colony defense is normally a behavior limited to the soldier caste. However, in these “ultra-eusocial” termites the worker caste has also evidently evolved self-sacrificing altruistic colony defense behavior. Although the salivary glands exhibited no peculiar hypertrophy or modification, we suggest that the mild sting-like quality of the bite may be due to a molecular component in the oral secretion or crop content of the workers.
