All infested Eximus now only require 3 scans for Codex Completion(since the Hives event). As well, to the scanner completionists like me, rare crawlers such as lobber crawlers and electric crawlers are found more frequently in survivals(not just the ones that are dropped by mutalist ospreys). If you want to get standard and eximus scans from them, a Dark Sector Survival is the way to go. Unfortunately, Nauseous Crawlers that are not dropped by mutalist ospreys are still only found on some infestation alerts.
