Beedrill mostly resembles a bipedal wasp; however, it only has four legs instead of six and lacks pigment pits. Beedrill's head is round with a slightly pointed mouth, with large, shiny red eyes and antennae in the shape of the number 7. Its legs are connected to its body by its thorax, and the first two are tipped with long, conical stingers. It stands on its other two legs, which are long, segmented and insect-like in shape. Beedrill has two pairs of rounded, veined wings, and another stinger on its striped abdomen.
They are highly territorial and normally live in colonies. Disturbing a swarm of Beedrill will cause the whole colony to attack. Beedrill is depicted as being very quick, so it's extremely difficult to avoid its attack after approaching its nest. They seem to be especially concerned with the welfare of Weedle and Kakuna, as shown by their tendency to respond aggressively towards those that disturb them.
Most Beedrill nest in forests and misty wooded areas. They can be encountered in Kanto and Johto.
Like bees, it might be possible that it collects nectar. However, it is also described to use sharp, poisonous stings to defeat prey, and then take the victim back to its nest for food.
