Habitat
Freshwater environments including temporary waters, small ponds, ditches, flooded areas, and larger permanent water bodies such as lakes. Specific preferences vary by : A. vernalis occupies temporary waters with rapid spring development, while A. robustus inhabits larger permanent water bodies.
Distribution
Records from Denmark (DK), Norway (NO), and Sweden (SE); broader distribution likely extends across Holarctic freshwater systems given -level records.
Life Cycle
A. vernalis exhibits rapid spring development synchronized with temporary water availability and produces resting for drought survival. A. robustus shows slower development adapted to stable permanent water conditions and does not require resting eggs. Developmental timing varies by in relation to permanence.
