Two-lined spittlebug facts, scientific name Prosapia bicincta

Have you ever seen patches of dry grass that when stepped on gave a squishy feeling? If yes, you might want to find out about a small bug in frothy foam spittle mass. You read it right; thats why it's named spittle, and you can notice two prominent orange lines horizontally on its wedge-shaped body. So that's how the two-lined spittlebug got its name. The identification is effortless as its common name describes its unique features. The scientific name of spittlebug is Prosapia bicincta. They belong to the leafhoppers family.

A spittlebug is commonly found on turfgrass species, but we can see centipedegrass has more feeding damage. These pests attack centipedegrass, bahiagrass, bermudagrass, St Augustine grass, and various ryegrasses. In addition, these pests infest grasslands and lawns primarily. Spittlebugs can found commonly in southeastern parts of the United States, from Texas to North Carolina. They require the optimal temperature to survive and perish in freezing weather.

Two-lined spittlebug Prosapia quite similar to leafhoppers only differs in color and shape. Its identification is relatively easy as it looks very different from a normal leafhopper.

What class of animal does a two-Lined spittlebug belong to?

The spittlebug belongs to a class of Insecta, just like grasshoppers, and falls under the family Cercopidae (leafhoppers).

How many two-lined spittlebugs are there in the world?

The exact population size of these spittlebugs is not recorded. However, these bugs have a higher reproductive rate. Each bug can lay up to 45 eggs in its short life span. So based on reproduction rate and brutal survival instinct, we can clearly say there no shortage of these bugs with appropriate natural resources such as tropical weather and abundance of turfgrass species.

Where does a two-lined spittlebug live?

The two-lined spittlebug lives where there is plenty of grass on which to feed. These bugs are predominantly found in spittle masses around the soil surface near the base of centipedegrass, St Augustine grass, bahiagrass, bermudagrass, and various ryegrass areas.

What is a two-lined spittlebug's habitat?

Two-lined spittlebug Prosapia is a Folivore. It depends on plants, grasses weeds, ornamental plants, and crops for feeding. These insects prefer a warm climate and active in spring and summer. However, they cannot survive cold weather. You can find them jump and hop across the lawn/grasses.

How long does a two-lined spittlebug live?

Adult spittlebugs live for 42 days under optimal temperatures of 72 F - 95 F (22.23-35 C). These insects have the shortest life cycle, with an ambitious life cycle from eggs to nymphs being 50 days as their survival depends on the climatic condition and favorable environment. Every year two generations are produced.

How do they reproduce?

The female, after mating with the male, moves to oviposition and lays eggs. It lays an average of 45 eggs in its lifetime. During overwintering season, orange-colored eggs are laid near roots of grass areas on the solid surface or under the leaf sheath/underneath the leaves or in the crack of the stem. The female usually lays eggs in clusters, At the egg stage, it takes 19 days to hatch, and the cream-colored spittle nymphs come out. These nymphs feed on host plant sap or leaf juices, causing the leaves to wilting patches. These juices are spitted out through breadthways into frothy foam spittle masses. The nymphs take 34 to 60 days to turn into adult spittlebug.

What is their conservation status?

This prosapia bicincta is abundant in nature. The pest easily infests the area once it starts attacking. So, this spittlebug is not listed under conservation status by ICUN as its population is stable.

Nymphs produce white foam that looks like snow on plant leaves. This insect sucks sap from host plants and using their breathing tubes to produce air bubbles in the clear white liquid that looks like spittle mass.

Spittle masses help to provide hydration as the exoskeleton is not yet developed and also provides protection from other predator species. In addition, studies have confirmed that the spittle mass is not poisonous.

It takes 76 days to complete the egg to egg life cycle under optimal temperature.
