Alabagrus stigma is a species of parasitoid wasp in the family Braconidae, first described by Brullé in 1846. As a member of the genus Alabagrus, it belongs to a group of braconid wasps known for their role as parasitoids of other insects. The species is documented in the Catalogue of Life and NCBI Taxonomy databases, with 35 observations recorded on iNaturalist. Specific ecological and biological details remain limited in available sources.
Apalonia
Apalonia is a genus of rove beetles in the family Staphylinidae, established by Casey in 1906. The genus contains at least 40 described species, placing it among the more species-rich genera within the aleocharine rove beetles. These beetles belong to the tribe Athetini, a large and diverse group characterized by small body size and complex morphological features. The genus has been documented in entomological collections, though detailed biological studies remain limited for most species.
Aulogymnus
Aulogymnus is a genus of chalcidoid wasps in the family Eulophidae, first described by Förster in 1851. Members of this genus are small parasitoid wasps, part of a diverse family that primarily parasitizes other insects. The genus has been recorded from Europe and Asia. Specific biological details for the genus as a whole remain poorly documented in accessible literature.

crustaceans
Crustacea is a major subphylum of arthropods encompassing approximately 67,000 described species, with estimates suggesting this represents only 1-10% of actual diversity. The group includes familiar aquatic forms such as crabs, lobsters, shrimp, krill, and barnacles, as well as terrestrial representatives like woodlice. Crustaceans are united by biramous (two-parted) limbs and characteristic larval development, often involving a nauplius stage. Current phylogenetic understanding places Crustacea as paraphyletic with respect to Hexapoda (insects and allies), with both groups now combined in the clade Pancrustacea. The subphylum exhibits extraordinary morphological diversity, ranging from the 100-micrometer Stygotantulus stocki to the Japanese spider crab with a 3.8-meter leg span.
Eremotylus subfuliginosus
Eremotylus subfuliginosus is a species of ichneumon wasp in the family Ichneumonidae, described by Ashmead in 1894. Members of the genus Eremotylus are recognized as parasitoid wasps, though specific biological details for this species remain limited. The species has been documented through a small number of observations on iNaturalist, suggesting it is either uncommon or underrecorded.
Heterhelus
Heterhelus is a genus of short-winged flower beetles in the family Kateretidae, containing at least four described species. The genus was established by Jacquelin du Val in 1858. Species in this genus are found in Europe and North America, with distribution records from Denmark, Norway, Sweden, and the United States.
Heteropogon stonei
Heteropogon stonei is a species of robber fly in the family Asilidae, described by Wilcox in 1965. The genus Heteropogon belongs to the subfamily Brachyrhopalinae. Robber flies in this genus are small to medium-sized predatory flies. Specific details about H. stonei's biology and ecology remain poorly documented in published sources.
Meronera
Meronera is a genus of rove beetles in the family Staphylinidae, established by Sharp in 1887. The genus contains at least four described species distributed in North America and Europe. Members of this genus belong to the subfamily Aleocharinae, one of the largest groups within rove beetles.
Microschatia
Microschatia is a genus of darkling beetles (family Tenebrionidae) found in arid regions of southwestern North America. The genus was established by Solier in 1836 and contains approximately 15 described species. These beetles inhabit dryland environments and are adapted to xeric conditions. The genus is taxonomically well-established within the Tenebrionidae, though detailed biological studies remain limited for many species.
Monocrepidius rudis
Neurotoma
Neurotoma is a genus of sawflies in the family Pamphiliidae, established by Konow in 1897. The genus contains approximately twelve described species distributed across Europe, Southeastern Asia, and North America. At least one Nearctic species, N. crataegi, has been documented feeding on hawthorn (Crataegus sp.) as larvae. The genus belongs to the suborder Symphyta, representing one of the more species-rich genera within the relatively small family Pamphiliidae.
Physegenua obscuripennis
Physegenua obscuripennis is a species of lauxaniid fly described by Bigot in 1857. The genus Physegenua contains small to medium-sized flies in the family Lauxaniidae, a group characterized by often patterned wings and bodies. Records of this species are sparse, with limited observational data available.
Rysepyris micidus
Rysepyris micidus is a species of wasp in the family Bethylidae, a group of small parasitoid wasps. Members of this genus are known to parasitize larvae of beetles and other insects. The species is characterized by its compact body form typical of bethylids. Specific biological details for this species remain poorly documented in published literature.
