Guinea Paper Wasp

Fascinating facts about the Guinea Paper Wasp

• Queens survive cold snaps far better than their sisters: a 15-day trial at 5 °C (41 °F) left 76% of queens alive versus only 17% of workers. The difference stems from higher sugar cryoprotectants and a 0.5 mm fat layer that insulates queens, letting them overwinter and extend the mating season.
• Temperature during development locks a wasp into queen or worker fate. June-emerging larvae kept at 26 °C with 16 h light and 8 h dark grew larger, more active ovaries, while those at 22 °C with 14 h light and 10 h dark kept smaller, less active ovaries. The shift likely follows a juvenile-hormone cue that tells the insect which caste to become.
• When the first brood hatches between May and July, some males emerge early alongside workers, called "early males". Colonies that produce more early males end up with more workers, cells, pupae and later emergences. Early males therefore act as a backup reproductive pool, ensuring the nest can keep going even if the queen dies in May, which is common. This strategy buffers the colony against queen loss and keeps the population flowing through the summer.
• Guinea paper wasps build modest nests, never exceeding about 500 cells and usually housing fewer than one hundred individuals. Because the nests are small and open-combed, they are so the wasps often huddle together in large winter aggregations in cracks, under bark or inside buildings.
• From the 1920s to the 1940s the Guinea paper wasp vanished from eastern Missouri, re-appeared in the 1960s-80s, then disappeared again after 1989. This on-and-off pattern hints at long-term cycles of abundance rather than a simple north-south shift.
