I saw a factoid somewhere that a typical moth carries +10,000 eggs. So insects have a “bounce back” ability lacking among, say, pandas. But then again, moths have always had this capability, so maybe it takes that many eggs just to hold populations steady even under optimal conditions.
Another observation on these lines was researchers saying the collection nets were yielding familiar species, but that less common ones seemed to have disappeared. Wasps and the like taking over other niches?
