Thyridanthrax fenestratus (Fallén, 1814) is a bombyliid with poorly understood biology. It was recently shown to locally but frequently parasitize Pemphredon fabricii (M. Müller, 1911) (Hymenoptera: Crabronidae), a crabronid wasp that abundantly nests in old Lipara-induced galls on the common reed Phragmites australis (Cav.) Trin. ex Steud., 1840. The parasitism modes in Bombyliidae and Thyridanthrax spp. are not uniform. Here, we report that Th. fenestratus switches facultatively between killing the host almost immediately (idiobiont strategy) and killing the host at a later developmental stage (koinobiont strategy). We document the koinobiont parasitoid strategy for a series of Th. fenestratus larvae parasitizing P. fabricii. We found that a significant portion of Th. fenestratus larvae spend winter as young larvae and start feeding on fully developed and defecated prepupae of P. fabricii only after the end of cold-induced winter diapause. The time needed for the development of Th. fenestratus larvae exceeds several times the time needed for pupation of P. fabricii prepupae; the parasitized prepupae, therefore, remain paralyzed until the parasitic larva completes feeding. Fungicides, which alter the pupation of the host larva, seem to have negligible effects on Th. fenestratus larvae. The ability to switch between the two parasitism strategies has already been reported for several Anthrax spp., though the ability to block the host in the defecated prepupa stage and prevent its pupation following cold-induced diapause is herein reported for the first time.

Dipara trilineata (Diparidae) is a widespread eastern North American parasitoid with apterous females and winged males. Despite its seemingly limited dispersal capabilities, phylogeographic analysis over southern Appalachia reveals little structure, with only limited population level isolation. DNA barcoding surveys also definitively associate the male of the species, which had previously been misattributed, and a description of the correctly associated male is provided.

Ooencyrtus mirus Triapitsyn & Power (Hymenoptera, Encyrtidae) is recorded for the first time in Europe. It was found parasitising eggs of the invasive true bug Halyomorpha halys Stål (Hemiptera, Pentatomidae). This parasitoid is part of the Ooencyrtus telenomicida species complex where accurate species identification requires molecular data. Using morphology, the identification of the Ooencyrtus species parasitising brown marmorated stink bug eggs in Greece is ambiguous, but the sequences of the standard DNA barcode region (COI) and ITS2 place them in O. mirus.

Ropalidia jemmaesp. nov. is described from the protected Ankafobe evergreen forest in central Madagascar. This species is characterized by a variable black and green body colour pattern and a unique nest architecture within the genus Ropalidia. The nests of this species have an inverted cell opening orientation that exposes the cell bottoms outwardly, mimics the tree bark, and provides excellent visual nest concealment.

The subfamilies Amicrocentrinae and Dirrhopinae (Hymenoptera, Braconidae) are two small, monogeneric braconid subfamilies whose species exclusively attack lepidopteran larvae. The phylogenetic placement of Amicrocentrinae as a member of the helconoid complex of subfamilies has been supported by morphological and nuclear Sanger sequence data. The subfamilial status of Dirrhopinae on the other hand has been subject to debate, although it has been suggested as closely related to the microgastroid complex based on morphology only. Here we generated for the first time genomic ultraconserved element data for members of the above subfamilies (Amicrocentrum seyrigi van Achterberg and Dirrhope americana Muesebeck) to assess their phylogenetic affinities using exhaustive taxon sampling that includes all but one of the currently valid braconid subfamilies. Our results strongly confirm the placement of both taxa within the non-cyclostome helconoid and microgastroid complexes, respectively.
(膜翅目，小蜂科)是两个小的单属小蜂亚科，其物种专门攻击鳞翅目幼虫。形态学和核Sanger序列数据支持了Amicrocentrinae作为helconoid亚科复合体成员的系统发育定位。另一方面，Dirrhopinae的亚科地位一直存在争议，尽管仅根据形态学就认为它与微胃复合体密切相关。本研究首次对上述亚科(Amicrocentrum seyrigi van Achterberg和Dirrhope americana Muesebeck)的成员进行了基因组超保守元素数据，利用详尽的分类群抽样评估了它们的系统发育亲缘性，其中包括除一个外的所有目前有效的副纲亚科。我们的研究结果有力地证实了这两个类群分别位于非环状螺旋状和微胃状复合体内。

Recent field surveys in the eastern Canary Islands (Spain), followed by contributions of new occurrence records through the citizen science platform iNaturalist.com and the social media photo repository Flickr.com have revealed the presence of an overlooked small carder bee species (genus Pseudoanthidium Friese (Megachilidae: Anthidiini)) on the islands of Lanzarote and Fuerteventura. Here, we combined morphology, DNA barcodes (mitochondrial cytochrome c oxidase subunit I, COI) and ecological data (distribution, altitudinal ranges and environmental niche classification) to describe this species as Pseudoanthidium (Pseudoanthidium) jacobiisp. nov. We provide an illustrated description along with diagnostic morphological characters to separate it from P. (P.) canariense (Mavromoustakis, 1954), the only other congeneric species known from the neighbouring islands of La Gomera, Tenerife and Gran Canaria and from which it is separated by a genetic distance of 2.7%. We also evaluated the extent of shared environmental niche space among the two Pseudoanthidium species, and our results show a significant difference in elevation range as well as a very small (less than 1%) overlap between the modelled climatic niche of P. jacobii and that of P. canariense. Given the extremely restricted geographic distribution and the fragile and isolated nature of the habitat and host plants of this new island endemic species, we assign it an IUCN conservation status of “EN” (endangered) and discuss avenues for future research on the ecology and conservation of wild bees in the Canary Islands and neighbouring regions.

Wing interference patterns (WIPs) are color patterns of insect wings caused by thin film interference. Thin film interference is the same phenomenon responsible for the refracted spectral colors sometimes visible on soap bubbles. Insect WIPs are static patterns due to the variable thickness of wing membranes and the colors produced depend on the thicknesses of wing membranes. While WIPs have been studied in several taxa of small insects, they have not been broadly adopted by insect taxonomists. We surveyed WIPs in one moderate-sized genus of parasitoid wasps, Parapanteles (Braconidae: Microgastrinae). Using an inexpensive microscope camera set-up and free imaging and analysis software, we detected consistent WIP differences between Parapanteles species. In some cases, WIPs can be used to diagnose sibling species that would otherwise require SEM images to differentiate or DNA barcodes. Wing interference patters are an underemployed character that may be similarly useful in many other taxa of small clear-winged insects.

There are numerous nomenclatural issues that have arisen from these descriptions. To resolve them, we have examined all relevant primary types and provide images of these specimens, as well as their labels. We recognize as valid the two “ vaccinii ” species, Loxaulus vaccinii (Ashmead, 1887) and Zopheroteras vaccinii (Ashmead, 1887), and list their synonyms. We also include the following new nomenclatural and taxonomic acts: Acraspis vaccinii Ashmead, 1887: lectotype by present designation; Callirhytis vaccinii Burks, 1979: species incertae sedis ; Andricus impositus Beutenmüller, 1918: revalidated status; Andricus verifactor Kinsey, 1922: new status.

Known nocturnal behaviors of bees in the superfamily Apoidea, including the genus Bombus , were almost exclusively of females. Here we report observations of active free-ranging male Bombus at night in the plant nursery of the Fushan Research Center, Taiwan, in April 2022. Nectar feeding by males at inflorescences was confirmed by tongue-licking in the absence of pollen collecting. The numbers of active female and male bumblebees during the daytime were close to equal. In contrast, only males were found to be active in the night. Our observations suggest that such nocturnal activity is facultative. This finding not only provides a rare case of nocturnal activity in free-ranging Bombus , but also demonstrates that such behaviors can vary between the sexes.
