The life cycles and microhabitats involved in aquatic stages of eleven Rhyacophila Stephens, 1836 species living in two neighboring Japanese mountain streams in Nara Prefecture, central Honshu, were investigated. Eight species had univoltine life cycles; seven species had spring to early summer emergence seasons. One species had an autumnal emergence. Four univoltine species had periods where no larvae or pupae were collected in aquatic stages, possibly a period of egg diapause. Three species had bivoltine life cycles, with early summer and autumn emergence seasons. Rhyacophila nipponica Iwata, 1927, R. manuleata AV Martynov, 1934, and R. shikotsuensis Iwata, 1927, in the nigrocephala species group Ross, 1956, have larvae which spend most of their larval stage in the hyporheos. The larvae of R. transquilla Tsuda, 1940, also inhabit the hyporheic zone, although the vertical microhabitat used by this species differed from the former three species. All four of these species have hyporheic larval stages, but in these species the first and final instar larvae reside on the surfaces of cobbles. The first instar larvae seem to live on stone surfaces immediately after hatching, and subsequently move to the interstices of sand. Final instar larvae live in the interstices of sandy bottom, and move to stone surfaces for pupation. Eleven species of the genus Rhyacophila had diverse life histories, microhabitat preferences, and experienced differing water temperature regimes during larval stages at the sites. Life history and habitat preference variation enhances the species richness of the genus and coexistence of species in upper stream of the Kinokawa River.
对生活在日本中部本州奈良县两条相邻山涧中的11种1836种Stephens的生活史和水生微生境进行了研究。8种具有单行生命周期;7种的出苗期为春至初夏。其中一个物种在秋季出现。四种单伏虫在水生阶段有一段时期没有幼虫或蛹被收集到，可能有一段时期的卵滞育。3种具有双周期的生命周期，分别为初夏和初秋出苗期。黑头蝇种组中的Rhyacophila nipponica Iwata (1927)， R. manuleata AV Martynov(1934)和R. shikotsuensis Iwata (1927)， Ross(1956)的幼虫在幼虫期的大部分时间都是在下卵室中度过的。1940年的transquilla Tsuda幼虫也栖息于下潜带，但其垂直微生境与前3种不同。这四种幼虫都有下潜幼虫阶段，但在这些物种中，第一和最后一龄幼虫居住在鹅卵石表面。一龄幼虫似乎在孵化后立即生活在石头表面，随后移动到沙子的间隙。末龄幼虫生活在沙质底部的空隙中，然后移到石头表面化蛹。11种嗜Rhyacophila在不同地点具有不同的生活史、不同的微生境偏好和不同的水温。生活史和生境偏好的变化促进了木川河上游属的物种丰富度和物种的共存。

The paper gives an overview of Trichoptera found as adults in mid-Cretaceous Burmese amber from about 100 million years ago. Fifty-eight extinct species are listed, three of which are still described here: Paduniella cretacea sp. nov. , Palerasnitsynus vilarinoi sp. nov. , Palleptocerus kuranishii sp. nov. The extinct subfamily Palerasnitsyninae stat. nov. of the family Xiphocentronidae is established and the extinct Bipectinata orientalis comb. nov. is transferred from the family Calamoceratidae to the family Odontoceridae. The extinct family LepidochlamidaeWang et al., 2022, stat. nov. is transferred to the superfamily Leptoceroidea. The fifty-eight caddisflies of Burmese amber are distributed among twenty-one genera and fourteen families, of which fifteen genera and four families are also extinct. The large time distance between extinct and extant organisms makes the assignment to the extant genera and families difficult, because the higher taxa are defined according to the species living today and often do not or hardly correspond to the earlier species and their adaptations. Furthermore, in line with the hypothesis of a Gondwanan origin of Burmese amber, some embedded Trichopterans are discussed as relict descendants of Gondwanan Trichoptera, e.g. the family Palleptoceridae and the Xiphocentronid subfamily Palerasnitsyninae.
本文综述了在距今1亿年前的中白垩世缅甸琥珀中发现的毛翅目成虫。已灭绝的物种有58种，其中仍有3种:Paduniella cretaceous sp. 11、Palerasnitsynus vilarinoi sp. 11、Palleptocerus kuranishii sp. 11。已灭绝的Xiphocentronidae科Palerasnitsyninae stat11 .已建立，已灭绝的Bipectinata orientalis comb。11月从Calamoceratidae转移到齿齿螈科。已灭绝的LepidochlamidaeWang et al.， 2022, stat. 11 .被转移到Leptoceroidea超科。缅甸琥珀的球蝇58只，分布于21属14科，其中15属4科也已灭绝。灭绝生物和现存生物之间的大时间距离使得对现存的属和科的分配变得困难，因为高级分类群是根据今天生活的物种来定义的，往往不符合或几乎不符合较早的物种及其适应性。此外，根据缅甸琥珀的冈瓦纳起源假说，我们还讨论了一些嵌入的trichopterae是冈瓦纳Trichoptera的遗存后代，如Palleptoceridae科和Xiphocentronid亚科Palerasnitsyninae。

Amidst a global biodiversity crisis, collecting data at large spatial scales can illuminate patterns. Community science can be an avenue to reduce costs, broaden the scope of sampling, and, most importantly, connect with members of the public who are interested in and impacted by long-term ecological change. In 2021, we formulated a community science project – The Caddisfly Collective. Our goal was to study the regional influences on the responses of stream caddisfly (Trichoptera) communities to urbanization in the United States and Canada. Community scientists helped us achieve this goal by collecting caddisflies across a wider geographic scale than we could have reached on our own. To build The Caddisfly Collective, we recruited participants through social media and other online forums. We mailed collecting kits with a USB-powered ultraviolet LED light, a collecting container, bottles of preservative, data sheets, and collection labels to each participant; participants mailed back specimens and completed data sheets. There was a 79.7% rate of follow-through from sign-up to collection. During the project, 63 participants set up light-traps near urban and non-urban streams in seven different North American geographic regions, collecting adult caddisflies at 141 sites across the United States and Canada. Most sites were in the Midwest region, while the fewest sites were in the Far North region. Urban areas, classified by land cover data, comprised ~29% of total sites. We hope the details of our project can help other interested scientists implement similar projects in the future, especially focused on ecologically important caddisfly communities.

Species-level identifications of the larval stages of caddisflies are available for only a limited number of taxa that are used currently in water-quality monitoring programs. This has been a long-lamented condition, but the proportion of species identifications available for aquatic forms that are used in these efforts has increased little over the past half-century. This is despite repeated and documented advantages that species-level identifications add to monitoring studies. Approaches to examining this question have ranged from anecdotal accounts of pollution tolerance among species within a genus to detailed analyses comparing information available through different hierarchical levels of taxonomy, from species to family. Justifications for not using species-level taxonomic resolution have ranged from financial considerations to suggestions that higher levels are equally as valid in showing trends as are species-level identifications. However, the evidence justifying the use of higher levels of taxonomy is lacking and more evidence favors the value of species-level identifications. Genetic techniques offer the promise of more larval-adult associations, more useful identification keys, and improved biological monitoring.

Caddisflies use four basic methods to ensure that newly-hatched larvae become aquatic insects. One is to lay the eggs underwater so larvae can start a free life immediately after hatching. Another method is to lay the eggs above water and the hatched larvae fall or wriggle into the water. Caddisflies from waters that dry out in summer often have a female diapause gradually becoming sexually mature and often do not lay their clutches until late summer or autumn, when rising water levels flood the eggs. The hatched larvae develop into pupae by March-May, from which adult caddisflies hatch again emergence beginning in spring. Some caddisflies from waters that dry out lay in summer and those eggs hatch soon after laying so it is as a larva that they survive the dry period.

Two new species of fossil Tarachoptera are described from Burmese amber and named as Tarachocelis emmarossae sp. nov. and Kinitocelis patrickmuelleri sp. nov. The new species are documented by photos and line drawings. An update of the hitherto described taxa of Tarachoptera is provided including information about the depository of type material. The phylogenetic position of Tarachoptera in the amphiesmenopteran clade is discussed. A hypothetical cladogram based on cladistic principles was constructed to demonstrate the phylogenetic relationship combining Tarachoptera, Trichoptera, and Lepidoptera. It might serve as guidance in the interpretation of fossil taxa and future discoveries.

Shrinking pupal cocoons of Rhyacophila lezeyi were often found during summer in Shibukuro Stream, a highly acidic mountain stream in northern Japan (pH = 2.82 on average). We performed both field surveys and laboratory rearing experiments to clarify the mechanisms of R. lezeyi cocoon shrinkage. The R. lezeyi cocoon shrinkage proportion increased in years with high stream water temperatures and was related to water temperatures before and after pupation at the study site. Approximately 90% of the prepupae and pupae inside the shrinking cocoons died during the rearing experiment, implying that cocoon shrinkage caused by high water temperature strongly influenced R. lezeyi pupal survival. Laboratory experiments showed that R. lezeyi ’s pupal cocoon membranes were semi-permeable and that the cocoon fluids were always hyperosmotic, indicating that water molecules can continuously enter the cocoon fluids from the stream water until the turgor of the cocoon wall is reached. However, the shrinking cocoons showed lower fluid volume and higher osmolarity than the normal turgescent cocoons. The reduction of osmotic gradient across the membrane during decreased stream flow due to less precipitation and/or the damage to the cocoon membrane and pupal body from high and fluctuating water temperatures and low pH are possible mechanisms for R. lezeyi pupal cocoon shrinkage.

New taxonomic, biological and faunistic data are presented for some species of sawflies occurring in southern Europe and North Africa. Pamphilius mediterraneus sp. nov. is described from Italy (Sicily). It belongs to the alternans sub-group of the alternans species group. Pristiphora omalos sp. nov. is described from Greece (Crete). It belongs to the depressa species group. New junior synonyms are Calameuta tazzekae Lacourt, 1991 of Calameuta gaullei (Konow, 1896), and Emphytus leucostomus Costa, 1890 of Allantus cingulatus (Scopoli, 1763). Periclista rufiventris Zombori, 1979 is moved from the subgenus Periclista to the subgenus Neocharactus. Ametastegia (Protemphytus) persica Khayrandish, Talebi & Blank, 2015 is recorded for the first time in Europe, from Italy (Sicily), and a key to West Palaearctic Protemphytus species provided. Allantus enslini (Forsius, 1918) is more widespread in southern Europe than previously recorded. An identification key distinguishes it from its closer West Palaearctic relatives. New hostplant records are for Halidamia affinis (Fallén, 1807) ( Rubia peregrina ), Janus compressus (Fabricius, 1793) ( Sorbus torminalis ), and Macrophya albicincta (Schrank, 1776) ( Centranthus ruber ). New distribution records are given for a few other species.

High altitude ecosystems are often home to endemic species that have evolved in isolation from their low elevation counterparts. In many cases, especially in insects, such mountain endemics are often apterous (due to their reduced ability to fly and disperse). In most cases, so far, these mountain endemics are genetically differentiated from lowland sister species or populations. During an excursion in Central Spain, we encountered two such strikingly different morphotypes of the rove beetle Lobrathium multipunctum (Gravenhorst, 1802) (Coleoptera, Staphylinidae, Paederinae). The morphotype from high elevation was smaller and paler than those at low elevation, which were slightly larger, darker and regularly coloured. The high altitude morphotype was earlier considered a separate species ( Lobrathium hispanicum Dodero, 1916) from its widespread lower-land counterpart ( Lobrathium multipunctum (Gravenhorst, 1802)) before their relatively recent synonymy. Using the cytochrome c oxidase subunit I (COI) barcode region, we tested whether these distinct morphotypes are distinct species. We found that their synonymy is supported, based on multiple species delimitation methods. We suggest that this phenomenon may be more widespread amongst insects and other organismal groups. We note that the presence of high altitude morphotypes which are phylogenetically nested within, or genetically identical to, widespread lowland species (regular morphotype) is rarely reported in the literature on beetles (and other insects). These findings thus highlight the need for caution when describing mountain endemics and further highlight DNA barcoding as a helpful tool for their study.

In many cases, especially in insects, such mountain endemics are often apterous (due to their reduced ability to fly and disperse). In most cases, so far, these mountain endemics are genetically differentiated from lowland sister species or populations. During an excursion in Central Spain, we encountered two such strikingly different morphotypes of the rove beetle Lobrathium multipunctum (Gravenhorst, 1802) (Coleoptera, Staphylinidae, Paederinae). The morphotype from high elevation was smaller and paler than those at low elevation, which were slightly larger, darker and regularly coloured. The high altitude morphotype was earlier considered a separate species ( Lobrathium hispanicum Dodero, 1916) from its widespread lower-land counterpart ( Lobrathium multipunctum (Gravenhorst, 1802)) before their relatively recent synonymy. Using the cytochrome c oxidase subunit I (COI) barcode region, we tested whether these distinct morphotypes are distinct species. We found that their synonymy is supported, based on multiple species delimitation methods. We suggest that this phenomenon may be more widespread amongst insects and other organismal groups.
