Our world, particularly North America, is home to myriad insects that sport a green hue. Many of these are capable of flight, while others are adept crawlers.
Certain green insects, like grasshoppers, possess the remarkable ability to leap.
Evolution has equipped these bugs with a green exterior for camouflage, a survival tactic that allows them to blend effortlessly into the leafy habitats where they reside or feed.
It’s fascinating that a bug’s life can commence as a nymph of a different color, only to transform into a green adult insect later.
Interestingly, while some species are uniformly green, others display a beautiful blend of various shades.
Let’s take a look at some common examples of insects that are either entirely or predominantly green in color.
1. Green Lacewings
The Green Lacewings, belonging to the Chrysopidae family, are a prevalent green insect found in North America, often growing to achieve a wingspan up to 60mm.
Although the North American Green Lacewings aren’t as big as their tropical counterparts, they can still seem larger when compared to other insects.
These insects are distinct for their green body color, ranging from a deep, vibrant green to a lighter, yellowish-green hue.
Many species feature captivating large golden eyes, although some can be a shade closer to brown.
Another characteristic trait of Green Lacewings is their translucent and slightly shimmering wings, adorned with distinct veins. These veins often mirror the insect’s green color, but sometimes they may showcase a mix of green and black.
2. Banana Cockroaches
The Banana Cockroaches, known scientifically as Panchlora nivea, are consistently found throughout the southern regions of the United States.
Originally from tropical environments, these roaches have migrated northward, extending their presence as far as South Carolina.
These roaches are particularly distinctive due to their unconventional green hue, often displaying shades of lime or bright green.
However, it’s interesting to note that young Banana Cockroaches do not start life green. They initially showcase a dark brown shade and transition to green as they age.
Uncommonly found within homes, these roaches are more likely to be spotted near fresh or decaying fruit in gardens or rummaging through dead plant matter.
These insects from the Panchlora genus are infrequently classified as pests since they generally favor outdoor habitats.
3. Tree Crickets
The Tree Crickets, belonging to the Oecanthinae subfamily, prominently feature a verdant green color throughout their body.
Being creatures of the night, they employ their green hue as a camouflage tactic, allowing them to blend seamlessly into the foliage of various plants while they rest.
Both the forewings and hindwings of these crickets mirror the green of their body. This coloration extends to their slender legs, while their antennae may also exhibit hints of green.
The cricket’s eyes usually also possess a touch of green or yellow.
Although found across all habitats in North America, a handful of Tree Cricket subspecies may bear a brown hue.
One of the quintessential examples of green Tree Crickets is the Snowy Tree Cricket. This species is almost completely green and typically measures around 0.6 inches in size.
4. Pure Green Sweat Bee
Exhibiting a predominant green hue, the Pure Green Sweat Bee, scientifically known as Augochlora pura, is truly distinct.
This bee species is native to the eastern regions of North America and is primarily active during the summer months.
Their unique color scheme comprises a green body and dark legs adorned with white hairs. These bees also feature large black eyes and translucent wings with a smoky tinge.
Typically, they can be observed until August each year. As autumn sets in, female bees retreat into dead wood or seek shelter under tree bark.
Interestingly, male Pure Green Sweat Bees have a shorter lifespan, dying off in the fall. They only make a comeback in the spring and early summer of the following year.
5. Brown-Winged Striped Sweat Bee
The bee species Agapostemon splendens, although primarily green, boasts a more expansive range across the United States compared to the Pure Green Sweat Bees.
Their habitat stretches from Montana to Texas, indicating the northernmost and southernmost points of their distribution.
