[header] How to identify a hornet [title] Observe a gray, oval-shaped object made of paper. [step] While it's not actually paper, it is a paper-like substance made from hornet saliva and wood. The nest houses eggs, and hornets are very protective of both their home and their eggs. <sep> (A) The nest is low in wattage, just above 25 percent high. [substeps] Hornets usually die in late summer if they are kept warm. (B) Hence, you really don't want to be caught near their nest lest they consider you a danger. [substeps] While it starts as a small, honeycomb-looking object, as the colony grows, the nest expands to an oval shape resembling a football, stalactite, or inverted teardrop. (C) The wasp nest contains a lighter nest than a hornet, and the oil evaporates quickly after beating the wasps. [substeps] Kohkens are larger than wasps and their droppings, then there is no difference between hornets and wasps. (D) Thus, the wasps' nest is what nests a wasps nest. Two large clumps of wasps from the same potter's area should be approximately the size of a wooden shoebox.
