PHOENIX - Two bee attacks in the Valley over the weekend serve as a reminder we have to remain cautious, particularly through the summer.
In one incident, a man was sent to the hospital after getting stung more than 200 times.
Can you tell the difference?
A side-by-side comparison with an untrained eye proves it's hard to tell the difference between honeybees and Africanized "killer" bees.
There are ways to distinguish between the two, though they are of the same species, according to the Africanized Honey Bee Extension & Education Program.
Territory around an Africanized bee colony spans about 120 feet, compared to a honeybees' territory of about 20 feet.
The Africanized bee swarm is smaller, but more of the bees will become aggressive if they feel required to defend themselves -- into the thousands.
That also makes an Africanized nest in your backyard or around your home harder to spot.
Experts warn if you're close enough to recognize the difference, you could be in danger of an attack.
But there isn't much we can do about it.
"There is nothing we'll be able to do about the Africanized bee population in Arizona today," said Robert Page, foundation chair of life sciences at Arizona State University. "They're here to stay."
