Synoeca cyanea
Synoeca cyanea, commonly known as marimbondo-tatu, is a swarm-founding social wasp. Native to Brazil and Argentina, "S. cyanea" is one of the largest and most aggressive species of social wasps and is feared in many rural areas. It begins its colony cycle in the early spring and continues until nest abandonment. Throughout its life, "S. cyanea" forage sugary substances and animal carcasses for food and wood pulp for its nest. "S. cyanea" is also known for its strong venom, which is enough to cause haemolytic activity.
