Coastal Flat-body

Agonopterix yeatiana, the coastal flat-body, is a small moth in the family Depressariidae native to coastal and calcareous grassland habitats across western and northern Europe, with records from Belgium, Denmark, and Sweden. Moths in the family Depressariidae, commonly called flat-body moths due to the depressed posture they adopt when resting with wings held flat against the surface, are associated predominantly with umbellifer plants of the family Apiaceae as larval hosts. Agonopterix yeatiana larvae feed on wild carrot (Daucus carota), wild parsnip (Pastinaca sativa), and related coastal and grassland Apiaceae species, inhabiting the open, often calcareous or sandy habitats where these plants grow. Adult moths have greyish-brown forewing with a distinctive pattern of spots and dashes and reach approximately 8–12 millimeters in wingspan. The species is classified as Near Threatened by the IUCN, reflecting declines associated with the loss of traditional hay meadow management, coastal grassland degradation, and scrub encroachment that eliminates the open, flower-rich grassland habitats supporting its host plants. Agricultural intensification has reduced wild umbellifer populations significantly across lowland Europe, reducing food resources for larvae of specialist moths like A. yeatiana.

Common thrips

<em>Aptinothrips rufus</em>, the common thrips, is a small insect in the order Thysanoptera, family Thripidae, recorded from five European countries including Denmark, Norway, and Sweden, as well as the United States. It is Not Evaluated on the IUCN Red List. This species is primarily a grass-feeding thrips, found on grasses and grassland vegetation across temperate regions. The name "rufus" refers to the reddish-brown coloration of adults. Like other thrips, adults are minute insects, typically 1–2 millimeters long, with fringed wings adapted for flight and dispersal across grass habitats. Populations can be locally abundant in grasslands during warm summer months. <em>Aptinothrips rufus</em> feeds by piercing plant cells and extracting sap, primarily from grass blades and stems. It typically completes multiple generations per year under favorable conditions. The species has limited direct agricultural significance compared to some other thrips pests, but plays a role in grassland ecosystems. Biological traits such as precise body weight, longevity, and egg production figures remain poorly documented in standardized scientific assessments.
