They vote differently. [EDIT] OK, OK http://en.wikipedia.org/wiki/Wasp http://en.wikipedia.org/wiki/Hornet

they are two different species

The width and order of the black and yellow stripes. (This was only after the bumble bee's attorney claimed a copyright and patent infringement while maliciously attacking the bumble bees livelihood, good name and reputation. The bumble bee won the case and the wasp and hornet had to change their stripes in a manner not to be confused with the bumble bee and were permanently forbidden to take any part or paid position in the pollen redistribution and botanical fertility business!!) LOL P.S. I really don't know!!

1) The term "wasp" can be used as a more general term, to call "any insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor ant." Wasps in the narrow sense and hornets are wasps in this broad sense. A "wasp" in the narrow sense "is any member of the aculeate family Vespidae". The true hornets make up the genus Vespa. "Hornet" is also a colloquial term for an American wasp. 2) "A wasp is any insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor ant. The suborder Symphyta, known commonly as sawflies, differ from members of Apocrita by having a broader connection between the mesosoma and metasoma. In addition to this, Symphyta larvae are mostly herbivorous and "caterpillarlike", whereas those of Apocrita are largely predatory or "parasitic" (technically known as parasitoid). The most familiar wasps belong to Aculeata, a division of Apocrita, whose ovipositors are adapted into a venomous stinger, though a great many species do not sting. Aculeata also contains ants and bees, and many wasps are commonly mistaken for bees, and vice-versa. In a similar respect, insects called "velvet ants" (the family Mutillidae) are technically wasps. A much narrower and simpler but popular definition of the term wasp is any member of the aculeate family Vespidae, which includes (among others) the genera known in North America as yellowjackets (Vespula and Dolichovespula) and hornets (Vespa); in many countries outside of the Western Hemisphere, the vernacular usage of wasp is even further restricted to apply strictly to yellowjackets (e.g., the "common wasp")."

The true hornets make up the genus Vespa, and are distinguished from other vespines by the width of the vertex (part of the head behind the eyes), which is proportionally larger in Vespa; and by the anteriorly rounded gasters (the section of the abdomen behind the wasp waist)." Source and further information: http://en.wikipedia.org/wiki/Hornet "A hornet is an insect. It may also mean: Insects: a colloquial term for an American wasp, for example the Bald-faced hornet, White-faced hornet or Cicada killer wasp."
