Do Fleas Have Antennae?

Fleas have two pairs of antennae that are located behind their eyes. These small antennae allow fleas to detect heat from living objects. These are microscopic and are smaller than the fleas’ eyes. These antennae are sensitive to heat and humidity, and they can also sense smell and touch. Fleas have no preference for a particular temperature, but they are most attracted to temperatures that are between 104degF and 122degC. Fleas will attach to any type of host that they find, and they can also detect heat from other hosts.

Fleas are small insects that range from one tenth of an inch to three-quarters of an inch in length. They have two pairs of antennae, a flat body, and six legs. Fleas do not have wings and can travel long distances by crawling and jumping. Fleas are able to hide in the fur of their hosts to avoid detection. They have a strong sense of smell and may not have eyes. The adult flea will move quickly through a host’s fur, which allows it to hide from human eyes.

Flea larvae are not attracted to light. They wait for the right moment to emerge from the cocoon. This is why a flea’s larva will spend days or weeks on a single host. Their larvae also incorporate debris into their cocoon, allowing them to blend in with their surroundings. Fleas can live for as long as three months, depending on the conditions of the environment.
