Types of insects in Alberta

Trying to list them all would be impossible. So below, you will find the most common and abundant bugs that live in Alberta. I did my best to find an array of different types, such as bees, beetles, flies, mantises, ants, etc.

8 Common Insects in Alberta:


#1. Common Green Bottle Fly

  • Lucilia sericata

Types of insects in Alberta

  • Adults have metallic blue-green or copper-green bodies.
  • They have black hair on their backs, black legs, and antennae. Transparent wings with light brown veins.
  • They’re slightly larger than houseflies.

The Common Green Bottle Fly is one of the most common and well-known insects in Alberta.

These bugs are not many people’s favorite, but they have some critical jobs in forensic, veterinary, and medical science! Their larvae or maggot stage can help scientists determine the time of death in investigations.

In their natural habitat, Green Bottle Flies are essential aids in decomposition, feeding on carrion and feces.

Surprisingly, they’re also pollinators. Some plants, like the Pawpaw (Asimina triloba), have adapted to attract them with flowers that have the color of drying blood and an odor of rotting meat.

These flies are incredibly prolific. A single female fly may produce 2,000 to 3,000 eggs in her lifetime. They reproduce quickly, too, completing their lifecycle in just 2 to 3 weeks.


#2. European/Western Honey Bee

  • Apis mellifera

Types of insects in Alberta

  • They are primarily red or brown with black bands and orange-yellow rings on their abdomens.
  • They have hairy thoraxes and slightly hairy abdomens.

The Western Honey Bee is one of the most common insects in Alberta.

Unlike most bee species, Western Honey Bees form perennial colonies which survive for years. These colonies comprise about 30,000 to 80,000 bees, most of which are female, including the queen and worker bees.

Defending the hive can cost these bees their lives. When a Western Honeybee stings, usually its barbed stinger becomes lodged in its target. The attached venom sac and musculature are pulled from the bee, resulting in the bee’s death.

Foraging is hard work! A single worker bee flies at about 15 miles per hour and usually visits 50 to 100 flowers in a single trip.

Despite all this effort, the average worker only produces about 1.5 teaspoons of honey in her lifetime.

This honey is tasty for humans but is also essential for the hive. Workers feed honey to the larvae and feed on it themselves during the winter in temperate climates.


#3. Monarch

  • Danaus plexippus

Types of insects in Alberta

  • Monarch butterflies have a wingspan of roughly 4 inches (10 cm).
  • Their recognizable coloring is a “stained glass” pattern of orange with black veins. White dots line the outside edge of the wings.
  • Caterpillars are plump, with black, white, and yellow bands and tentacles on each end of its body.

Monarchs are easily one of the most recognized insects in Alberta!

They are famous for their color pattern and migration. Look for Monarchs anywhere there is milkweed, which is the only food the caterpillars eat.

Most people are familiar with the declining population of Monarchs. Planting milkweed and other native flowering plants is the best way to help them.

Interestingly, Monarchs are toxic to most animals and at the very least, taste bad! This poison comes from the caterpillar’s diet, which is almost entirely made up of milkweed. Toxins from the milkweed plant stay in them, producing a bitter taste and poisonous effects.

During migration, usually in mid-September, you may even see groups of hundreds flying south!

#4. Seven-Spotted Ladybug

  • Coccinella septempunctata

Types of insects in Alberta

  • They have red bodies with six black spots and one big black mark on the middle of their wings (hence their name).
  • The head is black with two white dots.
  • They are also known as Seven-spotted Ladybird and C-7.

When you think of ladybugs, you probably picture something similar to the Seven-spotted Ladybug!

Almost everyone loves them because of the MASSIVE amounts of aphids they eat. This makes them very useful in controlling the pest population of aphids in grasslands and farms.

Surprisingly, this insect is NOT native to Alberta.

They were introduced here from Europe as a biological control against aphids. Interestingly, while they are thriving in North America, Seven-spotted Ladybugs are declining in their native ranges in Europe.

#5. Bald-faced Hornet

  • Dolichovespula maculata

Also called the Bald-faced Aerial Yellowjacket, Bald-faced Wasp, Bald Hornet, White-faced Hornet, Blackjacket, White-tailed Hornet, Spruce Wasp, and Bull Wasp.

Types of insects in Alberta

  • They have black bodies with ivory markings on their faces, legs, thoraxes, and abdomens.
  • Look for three white stripes at the ends of their bodies.

Bald-faced Hornets are named for the ivory markings on their face. Despite the name, these insects aren’t true hornets. They’re actually a type of yellow jacket.

These intimidating bugs don’t have a pleasant reputation in Alberta.

They aggressively defend their nests and can sting repeatedly. But while their appearance and nests can be scary, they’re pretty handy to have around (as long as the nest isn’t close to human habitation).

First, the adults feed on nectar and help to pollinate flowers. In addition, they also kill and eat other types of yellowjackets! Sometimes, in early summer, a nest will be so full of yellowjacket remains that it will have a yellowish cast! Unless their nest is somewhere you’ll come into contact with it, it’s best to leave them be.

I’m sure you have spotted one of their nests before. They are large, papery, and football-shaped. The queen builds these nests by chewing wood material and mixing it with her saliva to make a paste.

#6. Two-striped Grasshopper

  • Melanoplus bivittatus

Two-striped Grasshopper (Melanoplus bivittatus)

  • Adults are typically 1.2 to 2 inches (3 to 5 cm) long.
  • They are usually green or tan, with two pale yellow stripes running along the top of their bodies from above their eyes to the hind tips of their wings.
  • They have green or buff hind tibia with black spines.

These insects are well adapted to various habitats in Alberta!

Part of the reason they can call so many areas home is their diet. Two-striped Grasshoppers aren’t picky and will feed on grasses, herbaceous plants, woody plants, seed pods, flowers, and crops.

When food is scarce, Two-striped Grasshoppers will also scavenge on dead plants and animals. In addition, they occasionally resort to cannibalism!

These grasshoppers can be a lot of fun to find and catch. However, many insect lovers have found out the hard way that Two-striped Grasshoppers are quick to bite when handled. 🙂


#7. Boxelder Bug

  • Boisea trivittata

Boxelder Bug (Boisea trivittata)

  • Adults are relatively flat and elongate.
  • They are black or dark brown with reddish lines on the edges of their forewings, margins of their abdominal segments, and the center of their pronotum (plate-like structure behind their heads).
  • Their eyes are red.

Boxelder Bugs are native insects in Alberta.

As their name suggests, it’s common to find them on Boxelder trees, though they will also use Maple and Ash trees. These trees are the bug’s primary food source, and they feed on the leaves, flowers, twigs, and seeds.

You may spot some of them near your house during the fall. Groups of Box Elder Bugs seek out dry, sheltered locations to hibernate through the winter.

Box Elder Bugs sometimes fall prey to birds, spiders, rodents, and praying mantises, but they have developed unique techniques to stay safe. Their red markings and foul smells they release help ward off predators.


#8. Spruce Bug

  • Monochamus scutellatus
Monochamus scutellatus. (2023, October 16). In Wikipedia.
  • Adults are large-bodied and black with a white spot at the base of their wings.
  • Females may have white mottling on their wing covers.
  • They have strong mandibles, robust legs, a spine on each side of their prothorax, and very long antennae that may be twice their body length in males.

Also called White-spotted Sawyers, you’ll find these bugs living in Alberta in coniferous forests. They are most abundant where there are plentiful dead or damaged trees, like in fire-affected areas.

The reproductive methods of Spruce Bugs set them at odds with loggers.

Females use their strong mandibles to chew holes in the bark of dead or dying trees to deposit their eggs. When the eggs hatch, the larvae excavate tunnels in the wood while feeding on the inner bark, cambium, and outer sapwood.

Loggers find that these tunnels damage the wood and allow in wood-destroying fungi. However, these bugs are part of natural forest succession. They have been negatively impacted by certain logging practices like clear-cutting, which disrupts natural patterns.
