  1. Are those defensive secretions on the sides of its pronotum? Posted one month ago

      1. I think it is, but have never seen a ladybird beetle do this although I knew they were capable. It's a pretty cool defense mechanism called 'reflex bleeding'. The drops of goo contain bitter compounds and toxins, which make the insect taste bad and thus wards off potential predators. The can release up to 20% of their body weight per reflexive bleed, but if they do it too frequently, it reduces their fitness. Posted one month ago
