Acleris pulverosana
Acleris pulverosana is a synonym of Acleris hastiana, a species of tortricid moth in the family Tortricidae. The name was described by Francis Walker in 1863 but is not currently accepted as a valid species. Records exist from Belgium, suggesting it has been historically documented in western Europe. As a synonym, biological information attributed to this name should be verified against current taxonomy under Acleris hastiana.

Anthocoris nemorum
Common Flowerbug
Anthocoris nemorum is a predatory anthocorid bug native to Europe, commonly known as the common flowerbug. It is an important biological control agent in orchards and agricultural systems, preying on aphids, psyllids, mites, and other small arthropods. The species exhibits distinct oviposition preferences, laying eggs primarily on apple leaves near leaf margins, and shows preference for damaged leaves over healthy ones. Multiple generations occur annually, with adults overwintering and reproducing in spring.

Aphis urticata
dark green nettle aphid
Aphis urticata, commonly known as the dark green nettle aphid, is a species of aphid in the family Aphididae. It is associated with nettle plants (Urtica species), as suggested by its specific epithet. The species has been recorded in parts of Europe including Belgium and the Azores (São Miguel). Like other aphids, it likely feeds on plant phloem sap.

Arthrolips fasciata
Arthrolips fasciata is a minute beetle species in the family Corylophidae, originally described by Erichson in 1842. Records indicate presence in Belgium with some uncertainty, and the species has been observed 18 times on iNaturalist. Like other members of this family, it is among the smallest beetles, typically associated with decaying organic matter and fungal habitats. The genus Arthrolips is part of the diverse microbeetle fauna that remains understudied due to its diminutive size.

Bombylius ater
Bombylius ater is a species of bee fly in the family Bombyliidae, originally described by Scopoli in 1763. The species is currently recognized as a synonym of Bombylella atra, though it was historically placed in the genus Bombylius. Bee flies in this group are characterized by their hairy bodies, long proboscises for nectar feeding, and parasitic larval stages. The genus Bombylius includes species that are active primarily in spring and are known for their hovering flight behavior.

Borkhausenia nefrax
Borkhausenia nefrax is a species of concealer moth in the family Oecophoridae, described by Hodges in 1974. The genus Borkhausenia contains multiple species distributed across various regions, with some members known to have expanded their ranges through human-mediated transport. The species has been recorded in Belgium, though the quality of these records varies. Larvae of related Borkhausenia species feed on decomposed plant material.

Dieuches armatipes
Dieuches armatipes is a seed bug in the family Rhyparochromidae. Native to Africa, it has established populations in the Western Hemisphere including the Caribbean and Florida. The species was first documented in the Western Hemisphere from Grand Cayman and St. Kitts in 1993, with subsequent records from intercepted specimens in the Dominican Republic and Jamaica. It has since been confirmed on the Florida mainland and in Belgium.

Exapion ulicis
Gorse Seed Weevil
Exapion ulicis is a small seed-feeding weevil specialized on gorse (Ulex europaeus). Adults are light gray with a prominent snout roughly half the body length. The species is native to western Europe and has been introduced to New Zealand, California, Hawaii, and other regions as a biological control agent targeting invasive gorse populations. Larval feeding destroys seeds within pods, reducing plant spread, while adult feeding on stems and spines causes minor damage.

Leptometopa latipes
freeloader fly
Leptometopa latipes is a species of freeloader fly in the family Milichiidae. The species was described by Meigen in 1830. Members of the family Milichiidae are commonly known as freeloader flies due to their kleptoparasitic behavior, often feeding on the prey of other insects rather than capturing their own food. The species has been recorded from several locations in Europe including Belgium and the Azores (Flores, Pico, Terceira).

Macrosiphoniella tanacetaria
Tansy Aphid
Macrosiphoniella tanacetaria is a small sap-sucking aphid that feeds on tansy (Tanacetum vulgare). Unlike some congeners, it is not attended by ants and produces minimal honeydew. Its gut physiology differs markedly from ant-attended aphids: it lacks significant oligosaccharide synthesis for osmoregulation, instead producing erlose as its primary honeydew sugar.

Oedothorax
dwarf spiders
Oedothorax is a genus of dwarf spiders in the family Linyphiidae, subfamily Erigoninae, first described in 1883. The genus comprises approximately 39 species distributed across Europe, Asia, North America, and Africa. These spiders are characterized by their small size, typically measuring only about 2 mm in total body length. Males of certain species, such as O. trilobatus, exhibit distinctive cephalothoracic modifications including tumor-like swellings or horn-like extensions. The genus has gained scientific attention due to O. gibbosus hosting up to five different bacterial endosymbionts simultaneously, representing a unique system for studying host-endosymbiont interactions.

Pipiza quadrimaculata
Four-spotted Pipiza
Pipiza quadrimaculata is a hoverfly species in the family Syrphidae, first described by Georg Wolfgang Franz Panzer in 1802. The species epithet "quadrimaculata" (meaning "four-spotted") refers to characteristic markings on the wings or body. It belongs to the tribe Pipizini, a group of small to medium-sized hoverflies often associated with woodland and wetland habitats. The species has been recorded in Belgium with presence confirmed across multiple administrative regions.

Procambarus acutus
White River Crayfish
Procambarus acutus, commonly known as the white river crayfish, is a freshwater crayfish species in the family Cambaridae native to eastern North America. The species exhibits a disjunct native distribution spanning from the Atlantic Slope to the Gulf of Mexico drainages. It has been introduced to multiple regions outside its native range, including parts of Europe and Africa, where it poses potential ecological and economic risks. Two subspecies are recognized: P. a. acutus and P. a. cuevachicae.

Tinocallis takachihoensis
Japanese elm aphid
Tinocallis takachihoensis is an aphid species in the family Aphididae, originally described from Japan in 1972. It is closely related to the well-studied crapemyrtle aphid (Tinocallis kahawaluokalani), a specialist pest of crape myrtle trees in the southeastern United States. The species has been recorded in Belgium and the Azores (São Miguel), suggesting some capacity for dispersal or human-mediated introduction. Like other members of the genus Tinocallis, it is likely a specialist herbivore feeding on phloem sap of its host plants.
