The beech aphid (scientific name: Grylloprociphilus imbricator) is a woolly aphid species that is seen in North America, from Maine to Florida. It is known to appear in a dramatic fashion.
The coloration of the aphid is of a light shade of blue. White-colored, long, and waxy filaments cover its entire body and give it a woolly appearance.
It gathers in a colony in large numbers on small branches, twigs, and foliage undersides of the American beech tree.
Infested beech trees appear to be covered with snow and their branches and twigs look smaller. Populations of this species become apparent by July and increase significantly by October and colonies of this species look quite similar to those of the woolly alder aphid.
Along with its striking appearance, this species produces loads of sticky honeydew which is expelled onto foliage, plants, the ground, and branches. Honeydew is the excrement of this species and it is this plant sap whose amino acids and nutrients have been extracted by the insect's body.
Sooty molds (Scorias spongiosa fungus) colonize the aphid's honeydew and convert it into a black color. What's really interesting about this creature is its dance moves; it will raise its hind end and sway! When disturbed, the whole colony will produce this action which produces a dance-like movement.
Because of this dance, the species is also called the boogie-woogie aphid! Keep reading to get to know more about this skilled aphid.

The population of beech blight aphids has not been evaluated yet. However, we do know that they are abundant and face no significant threat. Their populations become apparent starting from July and become eye-catching by October!
Where does a beech blight aphid live?
This aphid has a light bluish coloration. These aphids gather together in a colony in large numbers on small branches, twigs, and the undersides of a leaf of the American beech tree.
The beech tree that it inhabits appears to be covered with snow and its twigs and branches look smaller as a result of the infestation. It occurs in North America, mainly in the eastern states of the USA from Maine to Florida.
What is a beech blight aphid's habitat?
This aphid inhabits beech trees that appear to be covered with snow. Their branches and twigs look smaller as a result.
This species excretes a lot of sticky honeydew, which is the plant sap whose amino acids and nutrients have been extracted by the insect's body. This honeydew is excreted upon plants, foliage, the ground, and branches.
Sooty molds (Scorias spongiosa fungus) colonize the aphid's honeydew and convert it into a black color. During winter, it is ordinary to see this fungal growth convert into a black mass.
This sooty mold can be tar-like and very thick if there is a large population of aphids. The sooty mold fungi do not enter the plants' epidermis.
It procures nutrients from the sugars present in the honeydew on the plants' surface only. An aphid produces copious amounts of honeydew and there is not enough evidence to prove that this creature affects the host plant negatively.
Who do beech blight aphids live with?
It resides in a colony of its kind on a branch, twig, or the underside of a leaf of the American beech. Its colony can be as long as 5 ft (152.4 cm)! Colonies of these aphids look similar to those of the wooly alder aphid.
How long does a beech blight aphid live?
A beech blight aphid (Grylloprociphilus imbricator) can live for two to three years. At a point in their development, they will try to kill and attack beneficial insects in their own colony!
How do they reproduce?
Beech blight aphids, when they mature (when their wings are fully grown), disperse and mate before the winter season. Winged females of this species lay eggs that last the whole winter season. The cycle begins in spring again.
A female can birth female nymphs without a male. Thus these insects can produce nymphs quickly and increase their population quite fast. The nymphs of these aphids are very defensive and will mass attack any predators by stinging them with their sharp mouthparts!
What is their conservation status?
These wooly aphids have not been evaluated by the IUCN yet. They do not face any major threats, except predators preying upon them or humans trying to get rid of them.

What do they eat?
Beech blight aphids are strictly herbivorous and feed upon saps of trees. Their mouthparts are utilized to drain the juices of the host plant.
Ants, fungus, and wasps, are typically interested in these aphid colonies as they want to obtain the honeydew as a food source because it's sugar-rich. Ants are even known to protect aphid colonies by driving away predators and parasites. Ants do not mingle with the colonies though.
Beech blight aphids are vulnerable to predators and parasites. The nymphs of these aphids mass attack any predators by stinging them with their sharp mouthparts. These nymphs can sting anyone who poses any threat to them or comes in contact with their skin.
Are they poisonous?
Beech blight aphids are not poisonous. However, they are still considered pests by humans. To get rid of them, horticultural oil sprays and insecticidal soap are commonly used. Imidacloprid can also be used. It is a systemic compound used, which is ingested by aphids when they are feeding on plant stems and foliage.
Would they make a good pet?
Beech blight aphids are pests and aren't kept as pets. The dance of these boogie-woogie aphids can be entertaining and fascinating to watch, but even then these insects are not kept as pets.

Are woolly aphids harmful to humans?
Beech blight aphids are considered pests by humans. They are not harmful to people. However, they may sting us if there is skin contact, but it is not fatal.
Moreover, these insects can cause damage to their host plant as their honeydew attracts fungus. During winter, any fungal growth converts into a black mass.
This sooty mold can be tar-like and very thick if there is a large population of aphids. It has been conjectured that these insects may kill their host small beech trees. It is also suggested that the feeding pressure due to this insect may result in distorted or smaller foliage.
