Green shiny beetles are seen in growing habitats across North America. They are common on the West Coast, in Northeastern habitats, and in the Mid-West.
A growing number of shiny beetles are adapted to living in various temperate and sub-tropical climates which means many species can live in almost any part of the world as well.
These beetles can exclusively feed on plants. Some are scavengers while others are omnivores. A few native green shiny beetles of North America are also known for eating feces and carrion.
A wide range of green tiger beetles is also known for feeding on bark and trees. These types of green shiny beetles can be highly detrimental to tree health.
Citruses and oak trees are among the most affected species in North America.
Green beetles can also have a reduced impact on trees and vegetation, depending on their species.
In terms of coloring, most green shiny beetles in the US are either light green or dark green with a shiny appearance.
A small number of these beetles have a multicolored body where green is combined with white, red, or yellow in most instances, especially on the elytra.
The following species of beetles have a green shiny body as a dominant trait or as a rare morph.
1. Japanese Beetle
The Japanese beetle (Popillia japonica) is imported from Japan. Unlike its native Japanese counterpart, this beetle creates large problems in the US where it eats vegetation without as many predators.
This species has copper-like elytra and a shiny green almost metallic thorax and head.
It also has black and white spots around its elytra which makes this multicolored beetle easy to identify.
Growing up to a size of 15mm, this beetle is very good at eating entire plant leaves. Only its veins remain untouched.
It lays eggs in the ground and the emerging Japanese beetle starts chewing on plant roots for food.
2. Six-spotted Tiger Beetle
The Six-spotted Tiger beetle (Cicindela sexguttata) is one of the shiniest green beetles found in North America.
Its body is completely metallic glossy green. It has large white mandibles which means the species is distinct and easy to identify.
This beetle is a known predator. It feeds on almost all small arthropods and includes spiders and caterpillars.
While present in all types of habitats, these beetles prefer sandy terrain to lay eggs in easier.
Growing to a size of at least 12mm, these beetles can be seen in open areas with plenty of sunlight. They are only seen in groups in areas with plenty of food.
3. Common Green June Beetle
The Common Green June beetle (Cotinis nitida) is a common green shiny beetle in states such as Georgia.
Beetles of this genus are only partially green as half of their body has a dark gold color.
The specie is known to feast on foliage. Unlike other beetles, this species also eats the veins of leaves practically leaving nothing behind.
Growing up to a size of 40mm, the species can be controlled with pesticides, especially since it emerges late in the season.
Common Green June Beetles only appear in the second part of June. This leaves sufficient time for gardeners and farmers to take preventive measures.
4. Dogbane Leaf Beetle
Dogbane Leaf beetles (Chrysochus auratus) get their names from their exclusive food, dogbane. Common in the Northwest, this species has a metallic shiny body.
The body has a shiny green nuance with iridescent reflections in direct sunlight. It can appear golden in certain spots depending on how light reflects off its body.
Bugs of this genus are toxic and many predators avoid them due to their bad taste and toxic nature.
They live on plants that are rich in toxins. They eat and absorb these toxins also storing them in the body so that a limited amount of natural predators would even consider attaching them.
5. Figeater Beetle
Figeater beetles (Cotinis mutabilis) have a dark green body with yellow bands on the sides of the elytra.
Bugs of this genus are common in Southwestern US. It’s also seen in gardens where it’s not seen as a major threat.
In extreme cases, this beetle has been responsible for devouring entire crops of fruit. It has been noted to eat grapes.
However, the Figeater beetle is mostly known for drinking sap from cacti and desert-loving trees.
It’s not seen as a major pest as it doesn’t mainly invade flowers in the garden or the lawn.
6. Fiery Searcher Beetle
The Fiery Searcher beetle (Calosoma scrutator) has a shiny uniform green elytra and a blue cephalothorax.
These are some of the most helpful types of green beetles in the world as they consume a wide range of pests.
They are known for eating moths and destructive caterpillars on crops and gardens.
Fiery Searcher beetles have a large body (often larger than 30mm) and long mandibles they can use against a wide range of insects.
Furthermore, these beetles also release strong chemicals which help keep some predators away. Other predators such as birds and shrews are known not to be deterred by these strong chemicals of the Fiery Searcher beetle.
7. Emerald Ash Borer
Emerald Ash Borers (Agrilus planipennis) have a metallic shiny uniform green body. These elongated borers are some of the most problematic bugs in the world of North America ash trees.
Most ash trees in North America are considered possible victims of this beetle and its expanding range.
Common in North America only for a few decades, beetles of this genus get under ash tree bark which they eat and lay eggs in.
With significant damage, ash trees start to die.
There’s little that can be done against these beetles they normally affect ash trees in the first 10 years of their lives which means they don’t yet reach their natural seeding age.
These beetles are known to attack young ash trees and their expanding range is a sign of trouble for green and black ash.
8. Rainbow Scarab
The Rainbow Scarab (Phanaeus vindex) has a shiny green color with yellow-brown nuances on the thorax.
Beetles of this genus are instantly-indefinable by their longhorn.
Found in Eastern US states, the Rainbow Scarab is a species known to eat animal dung. As a result, it should be avoided when it comes to direct handling as it can carry parasites.
Rainbow Scarabs eat all types of dung such as those of pigs, opossums, and dogs.
9. Green Immigrant Leaf Weevil
The Green Immigrant Leaf weevil (Polydrusus formosus) is a common species in temperate climates.
It has a vivid green or green-blue body with a central blue stripe on the elytra. The top of its head and its elongated snout are black.
Weevils of this genus are known for their damaging role to various leaves and should be removed when seen on trees in the backyard.
Hazel and oak trees are among the most exposed species to the impact of this species.
Green Immigrant Leaf weevils eat leaves entirely slowing down and even stopping the natural photosynthesis process of various hardwood trees.
10. Asian Oak Weevil
The Asian Oak weevil (Cyrtepistomus castaneus) has a uniform green color with visible grooves on the elytra.
The coloring of this species closely resembles the color of the oak leaves it lives on and which it consumes.
This type of weevil impacts oak trees and other species of trees such as chestnuts.
Its impact can be major but many measures can eliminate it or prevent it.
Insecticides are successfully used against these weevils and they can be applied as preventive measures on young trees as well.
Red oak and black oak trees tend to be the most affected by the species so it’s best to take extra caution when it comes to protecting these species.
11. Golden Buprestid Beetle
The Northwestern US territories are home to the Golden Buprestid beetle (Buprestis aurulenta).
