The Buzz About Bees! Know Your Local Pollinators
Southern Louisiana’s warm climate and abundant flowering plants make it an ideal habitat for various bee species. This identification guide focuses on three common bee types you’re likely to encounter in our region: honey bees, carpenter bees, and leaf-cutter bees. Each plays a unique role in our ecosystem and has distinct characteristics worth knowing.

Honey Bees
Where Are They Found And What Are They Looking For?
Honey bees (Apis mellifera) establish colonies in hollow trees, wall voids, and managed hives throughout Southern Louisiana. Thanks to our mild climate, honey bee colonies can remain active nearly year-round, with peak activity during spring and summer blooming seasons. These highly social insects collect nectar from flowering plants to produce honey, which serves as their food reserve during periods when flowers are scarce.
In Southern Louisiana, honey bees forage on native plants like Black-eyed Susans, coneflowers, and Goldenrod, as well as agricultural crops including citrus, strawberries, and cucurbits. A single colony may collect nectar from flowers within a 3-mile radius of their hive, making them highly effective pollinators across large areas.
Identifying Features
Honey bees measure about ½-inch long with distinctive golden-brown and black striped abdomens. Their bodies are moderately hairy, especially on the thorax, giving them a somewhat fuzzy appearance compared to wasps. One of their most distinctive features is the pollen baskets (corbicula) on their hind legs, which often appear as bright yellow or orange clumps when filled with collected pollen.
Honey bee colonies are highly organized with three distinct castes:
- The queen (larger, with an elongated abdomen)
- Drones (male bees with larger eyes)
- Workers (the most numerous, all female)
Their hives contain hexagonal wax combs arranged in parallel sheets and can house 20,000 to 80,000 individuals during peak season. When establishing new colonies, honey bees may form swarms—dense clusters of bees that temporarily gather on tree branches or structures while scout bees search for a new permanent nesting site.
Honey bees are generally docile when foraging but will defend their hive if threatened. Unlike wasps, honey bees can only sting once, as their barbed stinger remains in the skin, causing the bee’s death afterward.
Carpenter Bees
Where Are They Found And What Are They Looking For?
Carpenter bees (Xylocopa species) are large, solitary bees that drill perfectly round ½-inch diameter holes in untreated wood to create nesting galleries. In Southern Louisiana, they’re particularly active from early spring through summer and are commonly found around wooden structures including eaves, deck railings, fence posts, and outdoor furniture. Unlike termites, carpenter bees don’t consume wood—they excavate it solely for nesting purposes. Though this does not make them less dangerous for structures.
The female carpenter bee creates a tunnel that turns 90 degrees after the entrance and extends 4-6 inches along the wood grain. Within this tunnel, she constructs a series of brood cells, each provisioned with a ball of pollen and nectar before laying a single egg and sealing the cell. New adult bees emerge in late summer, and some may overwinter in the tunnels to begin the cycle again the following spring.
Carpenter bees are important pollinators in Southern Louisiana’s ecosystem, visiting a wide variety of flowering plants including salvia, lantana, passionflower, and many native wildflowers. They practice a unique “buzz pollination” technique where they vibrate their flight muscles to shake pollen loose from flowers, making them especially effective pollinators for certain plants.
Identifying Features
Carpenter bees are robust insects measuring ¾ to 1 inch in length, making them among the largest bees in Louisiana. The eastern carpenter bee (Xylocopa virginica), our most common species, has a shiny, hairless black abdomen that distinguishes it from similarly-sized bumble bees. Their thorax is covered with yellow, orange, or black hairs, and they have impressive mandibles adapted for drilling into wood.
Sexual dimorphism is pronounced in carpenter bees:
- Males have a distinctive yellow or white facial marking and cannot sting, but they display territorial behavior by hovering near nest entrances.
- Females have entirely black faces and possess stingers, though they rarely sting unless directly handled or threatened.
The entrance holes to carpenter bee nests are remarkably perfect circles about ½ inch in diameter, often with visible yellow pollen stains below and sawdust-like wood shavings during active excavation. Multiple generations may reuse and extend the same galleries over years, potentially causing structural damage if infestations are heavy.
Leaf-cutter Bees
Where Are They Found And What Are They Looking For?
Leaf-cutter bees (Megachile species) are solitary bees that nest in existing cavities such as hollow plant stems, abandoned beetle burrows in wood, masonry cracks, or even in the soil. Throughout Southern Louisiana, they’re active from late spring through fall, with peak activity during the warmest months. Unlike carpenter bees, leaf-cutters don’t excavate their own nesting cavities but instead find pre-existing ones.
What makes these bees fascinating is their unique nesting behavior—they cut nearly perfect circular or oval pieces from leaves and flower petals to construct their nests. The female leaf-cutter bee uses these plant materials to create a series of thimble-shaped cells inside her chosen cavity. Each cell contains a pollen and nectar provision upon which she lays a single egg before sealing it with more leaf pieces. A complete nest may contain 4-12 cells arranged in a linear series.
In Southern Louisiana, leaf-cutter bees commonly harvest material from roses, redbud, ash, and bougainvillea leaves, though they rarely cause significant damage to plants. As efficient pollinators, they visit a wide variety of flowering plants including native wildflowers, vegetables, and fruit trees, carrying pollen in a unique way that makes them especially valuable in our ecosystem.
Identifying Features
Leaf-cutter bees are medium-sized insects, typically measuring ⅜ to ⅝ inch long, with robust bodies that appear flattened compared to honey bees. Their most distinctive feature is how they carry pollen—unlike honey bees that transport pollen on their hind legs, leaf-cutter bees collect it on specialized hairs (scopa) on the underside of their abdomen. This gives their bellies a bright yellow or white appearance when laden with pollen and results in a characteristic flight pattern where the abdomen is often held higher than the thorax.
Most leaf-cutter species in Southern Louisiana have black or dark gray bodies with pale abdominal stripes created by bands of light-colored hairs. The females have modified mandibles specially adapted for cutting leaves with remarkable precision. While capable of stinging, leaf-cutter bees are generally non-aggressive and only sting if handled or trapped.
The most visible sign of leaf-cutter bee activity is their distinctive cutting pattern—nearly perfect circles or ovals about ½ to ¾ inch in diameter removed from leaf edges or petals. Multiple cuts may appear on the same leaf, though the bees typically distribute their harvesting across different plants to minimize impact.
Bees vs Wasps
Unlike aggressive wasps, these bee species are relatively docile and will only sting when threatened or handled. Learn to identify bees from wasps in our blog. Bees play a crucial role in our ecosystem as pollinators, and many species are experiencing population declines. Whenever possible, it’s best to leave bees undisturbed.
