What do antennas do for bugs

The antenna tapers from the base to the tip e. Moniliform - The round segments make the antenna look like a string of beads e.

Serrate - the segments are angled on one side giving the appearance of a saw edge e. Pectinate - The segments are longer on one side. This gives the appearance of a comb e. Sawflies related to wasps and Beetles. Clavate - the segments become wider towards the tip of the antenna e. Lamellate - the segments towards the end are flattened and plate-like.

Caterpillars and maggots are examples of insect larvae. Larvae often have soft exoskeletons that stretch so they can grow fast, and they go through a resting stage called a pupa before emerging as an adult. Insects that have incomplete metamorphosis have babies that look like small adults with no wings. They usually eat the same kind of food as the adults do.

Grasshoppers and cockroaches are two kinds of insects that have incomplete metamorphosis. Animal Diversity Web Cybertracker Tools. All rights reserved. Skip directly to main content.

The sum of the electrical potentials of the antenna to a given odor can be measured using an electroantennogram. In the case of the Monarch, it has been shown that antennae are necessary for proper time-compensated Sun compass orientation during migration, that antennal clocks exist in monarchs, and that they likely provide the primary timing mechanism for Sun compass orientation.

Crustaceans bear two pairs of antennae. The first pair are uniramous and are often referred to as antennules , while the second pair are biramous , meaning that each antenna is composed of two parts, joined at their base. In most adults, the antenna are sensory organs, but they are used by the nauplius larva for swimming. In some groups of crustaceans, such as the spiny lobsters and slipper lobsters, the second antennae are enlarged, while in others, such as crabs , the antennae are reduced in size.
