This microhabitat preference explains the frequent preservation of related species in amber and suggests similar ecological requirements for A. insolitus.
Distribution
North America; specifically recorded from the western Nearctic region excluding Beringia, with presence confirmed in California. The has been documented through GBIF and iNaturalist records.
Similar Taxa
- Aradus macrosomusA fossil from Baltic amber described by Heiss in 2014; differs in being significantly larger (name refers to 'large body') and having particular structural differences from . A. insolitus is an extant North species, while A. macrosomus is an extinct Eocene species.
- Other Aradus speciesThe Aradus contains multiple in North America that share similar flattened body forms and bark-dwelling habits; specific differentiation of A. insolitus from other extant species would require examination of genitalic and other morphological characters not available in the provided sources.
