Lifecycle and Growth

Egg, Nymph, Adult

1-2 weeks

Egg

Swallow bug eggs are laid in clusters, adhering to nest materials, incubating until nymphs emerge.

Clustered egg deposition
4-8 weeks

Nymph

Nymphs resemble smaller adults, feeding on bird hosts and molting five times to reach maturity.

Five molting stages for growth
6-12 months

Adult

Adults are wingless, feeding nocturnally on host birds, and reproducing to maintain population in nests.

Wingless nocturnal feeders

Dietary Habits

A proficient bloodsucker with specialized mouthparts, this insect feeds primarily on the blood of birds and occasionally mammals.

DIET TYPEDESCRIPTION
Primary DietFeeds mainly on swallow birds, extracting blood with its piercing mouthparts.
Secondary DietOccasionally consumes the blood of bats, adapting to available hosts in shared roosting areas.
OccasionalRarely feeds on human blood when bird hosts are scarce, highlighting its opportunistic feeding behavior.

Frequently Asked Questions

How long do Swallow Bug live?

Swallow Bugs typically live for several months to a year. Their lifespan depends on environmental conditions and availability of their host birds, particularly swallows. They can survive extended periods without feeding by entering a dormant state.

What do Swallow Bug eat?

Swallow Bugs primarily feed on the blood of birds, especially swallows. They are ectoparasites and rely on their avian hosts for nourishment. Occasionally, they may bite humans if bird hosts are unavailable, but they prefer birds.

Are Swallow Bug poisonous?

Swallow Bugs are not poisonous. While they can bite humans, they do not transmit diseases or inject venom. Their bites might cause mild irritation or itching, similar to other insect bites.

Are Swallow Bug endangered?

Swallow Bugs are not considered endangered. They are quite common, especially in areas where their host birds, like swallows, are plentiful. Their population is closely linked to that of their avian hosts.

What do Swallow Bug symbolize?

Swallow Bugs do not have a specific symbolic meaning. Unlike their host swallows, which often symbolize hope or renewal, Swallow Bugs are generally viewed as pests due to their parasitic nature.

Do Swallow Bug bite?

Yes, Swallow Bugs can bite. They primarily feed on bird blood but may bite humans if their preferred hosts are not available. Their bites can cause itching and mild irritation, similar to other insect bites.

What color are Swallow Bug?

Swallow Bugs are typically reddish-brown. They have a flat, oval-shaped body, which helps them hide in small crevices near bird nests. Their color can change slightly after feeding, becoming more reddish due to the ingested blood.

Does a Swallow Bug have wings?

Swallow Bugs do not have wings. They are wingless insects that rely on hiding near their bird hosts' nests and crawling to them for feeding. Their lack of wings distinguishes them from other insects that may also be found near bird habitats.

What does a Swallow Bug look like?

Swallow Bugs are small, about 5 millimeters long, with a flat, oval body. They are reddish-brown in color and resemble bedbugs. Their body shape allows them to hide in small crevices near their host birds' nests.

Is a Swallow Bug an insect?

Yes, a Swallow Bug is an insect. It belongs to the Cimicidae family, which also includes bedbugs. As an insect, it has a six-legged body structure, though it is wingless and adapted to a parasitic lifestyle on birds.
