The Bumelia Borer is a type of insect that poses a significant threat to various tree species. These pests are known for the damage they cause to trees by boring into their trunks, branches, and roots.

Gaining knowledge about the Bumelia Borer can help in identifying, preventing, and managing infestations in a timely and efficient manner.

As a wood-boring insect, the Bumelia Borer typically targets trees that are weak, drought-stricken, or diseased.

Some common signs of Bumelia Borer damage include holes in the bark, frass, or sawdust-like material around the affected area.

Keeping trees healthy and monitoring for early signs of infestation can save trees from destructive decay and even death caused by these pests.

Bumelia Borer Basics

Origin and Identification

Bumelia Borer, scientifically known as Plinthocoelium suaveolens, is a type of beetle from the family Cerambycidae and order Coleoptera.

These beetles are commonly found infesting trees, particularly bumelia trees.

Size and Range

  • Adult Bumelia Borer beetles typically measure around 1 inch in length.
  • They have a notable range across the Southern United States, especially in Texas and Florida ¹.

Life Cycle

Bumelia Borer’s life cycle consists of the following stages:

  1. Eggs: Female beetles lay eggs on the bark of host trees.
  2. Larvae: Once hatched, the larvae bore into the tree, creating tunnels and feeding on the wood.
  3. Pupae: After several months to a year, the larvae pupate inside the tree.
  4. Adults: The adult beetles emerge from the pupae and exit the tree, starting the cycle anew.

Comparing Bumelia Borer to other common tree borers:

Borer Type Size (Length) Common Host Trees Distribution
Bumelia Borer ~1 inch Bumelia trees Southern United States
Emerald Ash Borer 3/8″-1/2″ Ash trees Central and Eastern U.S., Canada
Old House Borer 5/8″-1″ Softwood trees United States
Bronze Birch Borer 1/4″-1/2″ Birch trees North America

By understanding the basics of the Bumelia Borer, you’ll be better prepared to identify and manage them in order to protect your trees from damage.

Mating Bumelia Borers

Habitat and Host Trees

Preferred Tree Species

The Bumelia Borer mainly prefers trees like:

  • Tupelo (Nyssa species)
  • Mulberry (Morus species)
  • Oak tree
  • Hickory
  • Gum Bully (Sideroxylon species)
  • Fir

These tree species provide a suitable habitat for the Bumelia Borer because of their sap, which provides nourishment for the insect.

Distribution in North America

The Bumelia Borer is primarily found in xeric habitats in North America. Some characteristics of xeric habitats include:

  • Low rainfall
  • Drought conditions
  • Limited water availability

In North America, the Bumelia Borer can be found across a wide range of states and provinces, making its presence a concern for tree health in the region.

Behavior and Impact

Feeding Habits

The Bumelia Borer, belonging to the Cerambycidae family, has distinct feeding habits. For instance:

  • Adults: They primarily feed on the leaves of host trees.
  • Larvae: They are known as trunk or root borers, tunneling into the wood of host trees.

Damage to Trees

Bumelia Borers can cause significant damage to trees:

  • Trunk damage: Larvae bore into the trunk, causing structural instability.
  • Root damage: Root borers weaken the tree’s ability to absorb nutrients and water.

As a result, infested trees may appear stressed, with wilting leaves and reduced overall growth. In some cases, severe infestations can lead to tree death.

Comparison Table: Bumelia Borer vs Other Borers

Borers Colors Family Target Damage Level
Bumelia Borer Orange Cerambycidae Trunk & Roots High
Net Borer Brown Cerambycidae Roots Moderate
Pine Borer Black-White Buprestidae Bark & Outer Trunk Low

Distribution in Southern U.S.

Florida and Georgia

The Bumelia Borer, a type of longhorn beetle, can be found in the southern states of the U.S., including Florida and Georgia. This insect primarily feeds on the gum bumelia tree, a native plant in these regions.

  • Found in: Florida and Georgia
  • Feeds on: Gum Bumelia

Arizona and New Mexico

Similarly, the Bumelia Borer is also present in Arizona and New Mexico. These states provide suitable habitats and host plants, such as gum bumelia, for the insect to thrive.

  • Found in: Arizona and New Mexico
  • Feeds on: Gum Bumelia

Comparison Table:

State Presence Host Plant
Florida Yes Gum Bumelia
Georgia Yes Gum Bumelia
Arizona Yes Gum Bumelia
New Mexico Yes Gum Bumelia

Management and Control of Bumelia Borer Infestations

Dealing with Bumelia Borer infestations requires a combination of preventive measures and active interventions.

These pests can cause significant damage to trees, but with the right strategies, their impact can be minimized. Here’s a guide to managing and controlling Bumelia Borer infestations:

Regular Monitoring:

  • Tree Inspection: Regularly inspect trees for signs of Bumelia Borer damage, such as holes in the bark, frass, or sawdust-like material around the affected area.
  • Traps: Use pheromone traps or UV light traps to monitor adult Bumelia Borer activity. These traps can help detect the presence of borers early on.

Cultural Control:

  • Tree Health: Maintain the health of your trees. Healthy trees are less susceptible to Bumelia Borer attacks. Ensure they receive adequate water, especially during dry periods, and fertilize them as needed.
  • Pruning: Remove and destroy infested branches to reduce the borer population and prevent further spread.

Chemical Control:

  • Insecticides: Apply insecticides to the bark of trees during periods when adult borers are active. This can help prevent females from laying eggs and can kill emerging adults. Always follow label instructions and consult with local agricultural extensions for recommended products.
  • Systemic Treatments: These are insecticides that are absorbed by the tree and can kill borers feeding within. They can be applied as soil drenches or trunk injections.

Biological Control:

  • Natural Predators: Birds, certain wasp species, and other insects can prey on Bumelia Borers. Encourage these natural predators by providing habitats or avoiding broad-spectrum insecticides that might harm them.
  • Nematodes: Beneficial nematodes can be introduced to the soil around affected trees. These microscopic worms can infect and kill Bumelia Borer larvae.

Physical Control:

  • Tree Wraps: Wrapping the base of young trees with a protective material can prevent female borers from laying eggs on the trunk.
  • Barrier Paints: These can be applied to wounds or pruned areas of trees to deter egg-laying.

Community Cooperation:

  • If Bumelia Borer infestations are a widespread problem in your community, consider working with neighbors and local organizations. Coordinated efforts can be more effective in managing and reducing borer populations.

Stay Informed:

  • Pest management recommendations can change as new research becomes available. Stay updated by consulting with local agricultural extensions, universities, or professional arborists.

  • ~Love it… Love the green , it’s a cutie~

  • Thank you for your input. I agree with you, if it is not the exact species is a closely related one.

    They are beautiful, but a little intimidating with their fast movements and suden flights.

    Sorry for the typos in my first mesage. I’ll try to avoid them in the future.

  • Haha I’m a bumelia.

  • Is Mr borer posionous? Saw one today.. beautiful green .. orange and black legs..

    The cocoons are indeed those of the Bumelia webworm moth (Urodus parvula). They have most often been reported from red bay trees. When the caterpillars are full-grown, they wander off of the host plants to spin their cocoons. I am trying to collect cocoons and hope to photograph the entire life cycle for a web page I am doing for the U.F. Entomology & Nematology Department’s “Featured Creatures” web site. I would appreciate learning of Gainesville locations of the cocoons.
