Infrabuccal pocket

from Wikipedia, the free encyclopedia

Infrabuccal pockets are pockets in the oral cavity of some insects . In wasps , they are special waste bags in which undesirable additions in the food and foreign bodies are collected.

Heinrich Kemper and Edith Döhring write: “ It stores unwanted solid remains and impurities in the food that have been held back by a fine bristle comb in front of the mouth opening. Dust and detritus particles that occur when cleaning the body are also stored in this waste bag, compressed and ejected from time to time in the form of solid pellets. “
Robin Edwards also claims that the infrabuccal pocket is occasionally emptied. However, since this apparently has no muscles of its own, it remains unclear by which mechanism this happens.
