What are cicada killers known for?

Cicada killers are known for their resemblance to larger wasps, often referred to as "monster" yellow jackets. This comparison stems from their size, coloration, and general appearance, which can make them appear intimidating. They belong to the wasp family and are notable for their aggressive look, but they are actually solitary and do not pose a significant threat to humans.

The other options do not accurately describe cicada killers. They are typically longer than one inch, which rules out the first choice. They do have wings, contradicting the third choice. Additionally, while cicada killers may feed on nectar, their primary behavior is centered around hunting cicadas, so stating that they feed primarily on nectar does not accurately represent their defining characteristics.
