Maine’s cold climate and long winters produce hardy bee species that emerge later in spring than their southern counterparts. Understanding the different types of bees in Maine helps you support local pollinators and create a bee-friendly garden. This guide covers the most common bees you’ll find in the Pine Tree State, from the familiar honeybee to the solitary miners.
Types Of Bees In Maine
Maine is home to over 270 species of native bees, plus the introduced honeybee. These bees play a crucial role in pollinating wildflowers, crops, and garden plants. Knowing which bees visit your yard helps you choose the right flowers and nesting spots.
Honey Bees In Maine
Honey bees (Apis mellifera) are not native to North America but are widely kept by beekeepers across Maine. They live in large colonies with a single queen and thousands of workers. These bees are generalist foragers, meaning they visit many types of flowers.
- Honey bees produce honey and wax, which beekeepers harvest
- They are active from early spring until late fall
- Colonies can survive Maine’s cold winters with proper management
- They are important for pollinating blueberries, apples, and cranberries
If you see a bee with a fuzzy golden-brown body and black stripes, it’s likely a honey bee. They are social and live in hives, often in wooden boxes managed by beekeepers.
Bumble Bees
Bumble bees are large, fuzzy, and often black with yellow or orange bands. They are native to Maine and are excellent pollinators, especially for tomatoes, peppers, and blueberries. Bumble bees can fly in cooler temperatures than honey bees, making them active earlier in spring.
There are several species of bumble bees in Maine, including the common eastern bumble bee and the rusty patched bumble bee, which is endangered. Bumble bees live in small colonies, usually in abandoned rodent nests or under grass clumps.
- They are social but have smaller colonies than honey bees
- Queens emerge in early spring to start new nests
- Workers are active through summer and fall
- Only the queen survives winter by hibernating
Identifying Bumble Bees
Look for a round, fuzzy body with distinct color patterns. The common eastern bumble bee has a yellow thorax and a black abdomen with a yellow band. The rusty patched bumble bee has a rusty-red patch on its abdomen.
Mason Bees
Mason bees are solitary bees that nest in hollow stems or holes in wood. They are named for their habit of using mud to seal their nest chambers. Mason bees are excellent early-spring pollinators, emerging when fruit trees bloom.
There are several species of mason bees in Maine, including the blue orchard bee. They are smaller than honey bees and have a metallic blue-black color. Mason bees do not produce honey and live alone.
- Each female builds her own nest
- They are very efficient pollinators for apples, cherries, and blueberries
- They are docile and rarely sting
- You can attract them by providing nesting blocks or hollow stems
How To Support Mason Bees
Place a mason bee house in a sunny, sheltered spot. Use tubes made of paper or bamboo, or drill holes in a block of wood. Clean the house each year to prevent mites and diseases.
Leafcutter Bees
Leafcutter bees are solitary bees that cut circular pieces from leaves to build their nests. They are medium-sized, with a black body and pale bands on the abdomen. Leafcutter bees are active in summer and are excellent pollinators for alfalfa, carrots, and other crops.
These bees are common in Maine gardens, especially where roses or other soft-leaved plants grow. They use the leaf pieces to line their nest cells, which are in hollow stems or cavities.
- They are solitary and non-aggressive
- Females carry pollen on the underside of their abdomen
- They are important for pollinating vegetables and flowers
- They nest in pre-existing holes or tunnels
Leafcutter Bee Damage
You may notice half-moon-shaped cuts on rose leaves. This is harmless to the plant and indicates leafcutter bees are nearby. Do not use pesticides on affected plants.
Sweat Bees
Sweat bees are small, often metallic green or blue, and are attracted to human sweat for salt. They are solitary or semi-social and are common in Maine during summer. Sweat bees are important pollinators for wildflowers and garden plants.
There are many species of sweat bees in Maine, ranging in size from tiny to medium. They are often mistaken for flies due to their metallic sheen. Sweat bees are generally harmless but may sting if handled.
- They are attracted to perspiration
- They nest in the ground, often in bare soil
- They are active from late spring to early fall
- They are important for pollinating clover and other small flowers
Managing Sweat Bees
If sweat bees bother you while gardening, wear light-colored clothing and avoid scented lotions. They are beneficial and should not be killed.
Carpenter Bees
Carpenter bees are large, black bees that resemble bumble bees but have a shiny, hairless abdomen. They are solitary and nest by drilling holes into wood, including decks, fences, and eaves. Carpenter bees are common in Maine and are important pollinators for some flowers.
Male carpenter bees are territorial and may hover near people, but they cannot sting. Females can sting but are not aggressive. They are most active in spring and early summer.
- They drill perfectly round holes into wood
- They prefer unpainted, soft wood
- They are important for pollinating passionflowers and other plants
- They can cause cosmetic damage to structures
Preventing Carpenter Bee Damage
Paint or stain exposed wood surfaces. Fill existing holes with wood putty or caulk. You can also install traps designed for carpenter bees.
Mining Bees
Mining bees, also called andrenid bees, are solitary bees that nest in the ground. They are among the first bees to emerge in spring, often before bumble bees. Mining bees are small to medium-sized, with a fuzzy brown or black body.
There are many species of mining bees in Maine, each with specific flower preferences. They are important for pollinating early-blooming trees and wildflowers. Mining bees are docile and rarely sting.
- They dig tunnels in bare soil or sandy areas
- Females collect pollen and nectar for their young
- They are active for only a few weeks each year
- They are crucial for early spring pollination
Supporting Mining Bees
Leave patches of bare, undisturbed soil in your garden. Avoid tilling or mulching these areas in spring. Plant early-flowering trees like willow and maple.
Yellow Jackets And Wasps
Yellow jackets and wasps are often mistaken for bees but are actually different insects. They are smooth-bodied, with narrow waists, and are more aggressive than bees. Yellow jackets are social and build paper nests in the ground or in walls.
While they are not bees, they are sometimes grouped with them. Yellow jackets are predators that feed on other insects, but they also visit flowers for nectar. They are common in Maine during late summer and fall.
- They are not effective pollinators
- They can sting multiple times
- They are attracted to sugary foods and garbage
- They are important for controlling pest insects
Distinguishing Yellow Jackets From Bees
Yellow jackets have bright yellow and black stripes, a smooth body, and a narrow waist. Bees are fuzzy and have a thicker body. If you see a nest in the ground, it is likely yellow jackets.
