Habitat
Deciduous and mixed forests; shrubland; moist meadows. High-elevation recorded at 2867–3075 m in mountainous regions of Northwest China.
Distribution
Global distribution across six biogeographic regions: Palaearctic (167 ), Afrotropical (125), Oriental (129), Nearctic (40), Neotropical (30), and Australasian/Oceanian (27). Nearctic records include areas south of the maximum extent of the Laurentide Ice Sheet, with new distributional data for 18 Nearctic .
Seasonality
activity observed July–August in Northwest China; attracted to light traps during summer months.
Life Cycle
soil-dwelling. involves selective acetylation of α-tubulin in kinetochore microtubules, with acetylation lagging behind polymerization in nondividing but occurring within 5 minutes in spindle microtubules.
Behavior
attracted to light traps.
Ecological Role
may function as soil-dwelling or ; some reported as agricultural pests.
Human Relevance
sometimes harmful to agricultural and ornamental plants.
