Aeshna juncea
Common Hawker, Moorland Hawker, Sedge Darner
Aeshna juncea, known as the Common Hawker, Moorland Hawker, or Sedge Darner, is a large hawker dragonfly with a Holarctic distribution spanning the Palearctic from Ireland to Japan and northern North America. It is one of the larger Aeshna species and is strongly associated with acidic bog habitats, particularly in Scotland where it is a prominent bog specialist. The species has a flight period from June to early October. Recent genomic research has revealed that Alaskan populations underwent population bottlenecks during the most recent ice age, and the species has been used as a model for studying genome size variation in Odonata driven by transposons and repetitive elements.

Haustoriidae
Haustoriidae is a family of amphipod crustaceans characterized by stout, robust bodies adapted for burrowing in sandy sediments. They are dominant members of intertidal and shallow subtidal sandy beach communities along the Atlantic coast of North America, with some species extending into the Gulf of Mexico and Pacific coast. The family radiated during the Eocene, with the Pacific-endemic genus Eohaustorius representing the most basal lineage, diverging approximately 31 million years ago. Haustoriidae are distinguished from other amphipod families by their specialized morphology for sand-burrowing and their limited dispersal capabilities, which have resulted in strong population structure and cryptic diversity across their range.

Plectrocnemia
tube maker caddisflies
Plectrocnemia is a genus of tube maker caddisflies in the family Polycentropodidae comprising more than 120 described species. Larvae are aquatic predators that construct silken capture nets to intercept prey. The genus has been extensively studied for its larval silk production, vibration-mediated predatory behavior, and population genetics. Species occur across Europe and into western Asia, with detailed biological information available for several well-studied species including P. conspersa and P. brevis.
