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.

slender entrophs
Campodeidae is a family of small, pale, eyeless hexapods in the order Diplura, distinguished by two long, many-segmented cerci at the abdomen tip. The family contains at least 30 genera and approximately 280 described species, distributed across soil and cave habitats worldwide. Members range from 5–12 mm in length, with the largest species being the cave-dwelling Pacificampa daidarabotchi from Japan. Abdominal spiracles are absent. The family exhibits diverse ecological strategies, with many species adapted to subterranean environments showing troglomorphic features such as elongated appendages and enhanced sensory structures.
Collembola
springtails
Collembola (springtails) are minute hexapods, traditionally grouped with insects but now recognized as a distinct class of non-insect hexapods. They are among the most abundant soil arthropods globally, with estimates of 200–1,800 individuals per cubic decimeter of forest soil. Most species measure 1–3 mm, though some reach 6 mm and the largest known species attains 17 mm. They occupy diverse habitats including soil, leaf litter, caves, rodent burrows, intertidal zones, ant and termite nests, freshwater surfaces, and snow fields. The group is defined by several unique morphological features: a ventral collophore on the first abdominal segment, a furcula (springing organ) on the third or fourth abdominal segment in most species, internal mouthparts (entognathy), and fused tibio-tarsal leg segments. They exhibit simple metamorphosis and continue molting throughout adult life, up to 50 times.
Entomobryomorpha
Elongate Springtails
Entomobryomorpha is one of three recognized orders of Collembola (springtails), distinguished by their characteristically slender, elongate body form. Members of this order typically possess either long legs and antennae with well-developed furculae, or short legs and antennae with elongated bodies that separate them from other springtail groups. The order was formerly treated as the superfamily Entomobryoidea and was grouped with Poduromorpha under the paraphyletic "Arthropleona." Current systematics recognizes Entomobryomorpha, Poduromorpha, and Symphypleona as equally distinct lineages at ordinal rank.
Isotoma
Waterfall Springtails
Isotoma is a genus of springtails (Collembola) and the type genus of the family Isotomidae. These small, wingless hexapods are commonly known as Waterfall Springtails. The genus contains multiple species distributed across various habitats, with some species studied for their dietary biology and metabolic responses. Springtails in this genus possess the characteristic furcula (springing organ) that enables their common name.
Pseudachorutes
Pseudachorutes is a genus of springtails in the family Neanuridae, containing more than 50 described species. These small hexapods are distributed across diverse biomes including arctic, tropical, and desert regions. As members of the subfamily Pseudachorutinae, they represent a well-established lineage within the Poduromorpha order.
