Acyrthosiphon lactucae
Prickly Lettuce Aphid
Acyrthosiphon lactucae is an aphid species in the family Aphididae, commonly known as the Prickly Lettuce Aphid. It belongs to the genus Acyrthosiphon, which includes several economically significant agricultural pests. The species was first described by Passerini in 1860. Unlike its congener Acyrthosiphon pisum (the pea aphid), which has been extensively studied, relatively little specific research has been published on A. lactucae. Available records indicate presence in parts of Europe including Norway, Sweden, and the Portuguese archipelago of Madeira.
Amaurorhinus bewickianus
Amaurorhinus bewickianus is a weevil species in the family Curculionidae, endemic to the Madeira archipelago. It was first described by Wollaston in 1860 and has been recorded from Madeira Island and the nearby Desertas Islands. The species belongs to a small genus of flightless weevils with restricted distributions in the Macaronesian region. Its island endemism and apparent absence from mainland Europe suggest limited dispersal capability.
Blacus ruficornis
Blacus ruficornis is a species of parasitoid wasp in the family Braconidae, subfamily Blacinae. The species was first described by Christian Gottfried Daniel Nees von Esenbeck in 1811. It belongs to a genus characterized by specific morphological traits including reduced wing venation and particular antennal structures. Records indicate presence in Northern Europe and on Madeira Island.
Hyadaphis coriandri
coriander aphid
Hyadaphis coriandri is a species of aphid specialized on coriander (Coriandrum sativum), where it is considered a major pest. It has been documented as a prey species for the ladybird beetle Menochilus sexmaculatus in laboratory biocontrol studies, though it supports predator development with reduced growth metrics compared to alternative aphid hosts. The species has a wide geographic distribution including parts of Asia, Europe (Madeira), and North America (Hawaii, conterminous United States).
Metanotalia
Metanotalia is a genus of parasitoid wasps in the family Encyrtidae, established by Mercet in 1921. The genus belongs to the subfamily Encyrtinae and is characterized by features of the mesosoma and metanotum. The type species, Metanotalia maderensis (Walker), was originally described from Madeira. Members of this genus are parasitoids, though specific host associations remain poorly documented in published literature.
Metanotalia maderensis
Metanotalia maderensis is a species of parasitoid wasp in the family Encyrtidae, originally described by Walker in 1872 as Ectroma maderense. It is endemic to the Madeira archipelago in the North Atlantic Ocean. The genus Metanotalia is a small group within the Encyrtidae, a family known for their role as parasitoids of scale insects and other hemipteran pests. Specimens of this species are held in the University of California, Riverside (UCR) Encyrtidae collection, one of the largest collections of this family globally.
Myospila meditabunda
Myospila meditabunda is a muscid fly described by Fabricius in 1781. It belongs to the subfamily Mydaeinae within the family Muscidae, a group of true flies commonly known as house flies and their relatives. The species has been recorded from multiple localities across northern Europe including Denmark, Norway, and Sweden, as well as from Madeira Island and the northeastern United States (Vermont).
Pteroxanium kelloggi
Pteroxanium kelloggi is a bark louse species in the family Lepidopsocidae. It has a distinctive brownish-orange coloration with white spots. The species has been recorded from western Europe and Madeira, with additional distribution records from North America, South America, and Australasia. It feeds on a variety of woody plants including ash, cedar, gorse, ivy, larch, oak, pine, and yew, and has also been observed on rhododendrons and decayed wood substrates.
Spelobia
lesser dung flies
Spelobia is a genus of small flies in the family Sphaeroceridae (lesser dung flies), established by Spuler in 1924. Species in this genus are terricolous, inhabiting the leaf-litter stratum of forest ecosystems. Some species, such as Spelobia polymorpha from Madeira, exhibit poor flying ability and have become island endemics. The genus is distributed across Europe including Scandinavia and has been introduced to other regions.
