Biology and Behavior

Life Cycle

Mexican honey wasps, also known as Brachygastra mellifica, are social insects that undergo a complete metamorphosis:

  • Eggs: Queens lay eggs in hexagonal cells within the nest.
  • Larvae: The hatched eggs grow into larval stage and are fed by worker wasps.
  • Pupae: The larval stage transitions to pupae as they develop in their cells.
  • Adults: Adult wasps emerge as workers, males, or future queens.

Diet and Foraging

These wasps are known for their role as pollinators and foragers. A few key aspects of their diet and foraging behavior include:

  • Nectar: Wasps primarily feed on nectar from various plants, contributing to pollination.
  • Insects: They also consume insects as a protein source, particularly for their developing larvae.
  • Cooperation: Foragers rely on teamwork to collect and bring food back to the nest.

Social Structure

The social structure of Mexican honey wasps consists of different castes with distinct roles:

  • Queens: Reproductive females responsible for laying eggs and establishing the nest.
  • Workers: Infertile females who carry out tasks such as foraging, feeding larvae, and maintaining the nest.
  • Males: Their main role is to mate with the queens, after which they die.

Pros of Mexican honey wasps as pollinators:

  • Less aggressive compared to other wasps, often ignoring human activity.
  • Efficient in pollinating plants due to their nectar-based diet.

Cons of Mexican honey wasps as pollinators:

  • Limited geographic range (from Texas to Nicaragua).
  • Less well-known compared to honey bees, leading to fewer studies on their pollination efficacy.

Feature Honey Bees Mexican Honey Wasps
Aggressiveness More aggressive Less aggressive
Geographic range Widespread Texas to Nicaragua
Pollination efficiency Well-studied Less-studied, but efficient
Social structure Queens, workers, males Queens, workers, males

Honey Production and Pollination

Nesting Habits

Mexican honey wasps are social insects, building paper nests in the canopies of trees and shrubs. They create a sophisticated hierarchy within their colonies and use strong nest-building skills to maintain well-fortified homes.

Pollination and Foraging Plants

These wasps aid in the pollination of various plants, such as avocados. They collect nectar and pollen from nearby flowers, which helps them produce honey. Their natural preference is to forage within 300 feet of their hive, so the arrangement of hives is crucial for effective pollination.

Some plants Mexican honey wasps might pollinate:

  • Avocados
  • Citrus fruits
  • Other fruit trees

Obtaining and Consuming Mexican Honey Wasp Honey

Wasps produce honey in relatively small quantities, using nectar as a primary ingredient. Consuming Mexican honey wasp honey requires care and knowledge about their potential stings. Approach their nests with caution to gather honey.

Pros of Mexican honey wasp honey:

  • Unique flavor
  • Ecologically important

Cons of Mexican honey wasp honey:

  • Smaller quantities produced
  • Risk of stings
Feature Honey Bees Mexican Honey Wasps
Pollination range Several miles but prefer 300 feet Prefer within 300 feet of their hive
Predominant honey production Yes No, smaller amounts
Risk of stings Less severe, allergic reactions possible Potentially more severe

Interactions with Other Species

Beneficial Role

Mexican honey wasps are important pollinators, similar to bees. They have some key differences from honey bees, like being smaller, almost all black in body color, and not very hairy1. They are:

  • Social insects
  • Less aggressive than honey bees
  • Commonly found in trees and shrubs1

As pollinators, Mexican honey wasps share similar benefits with stingless bees, such as helping in the pollination of various plants and crops. They perform this beneficial role while being less aggressive and rarely causing any harm to humans.

Pests and Predators

Mexican honey wasps may have some natural predators, like ants[^5^]. The wasp larvae could be targeted as valuable food sources for predators such as these. The limited aggressive behavior of the wasps, compared to honey bees, could make them more vulnerable to predation from ants and other insect predators.

Characteristic Honey Bees Mexican Honey Wasps
Size Larger Smaller1
Body color Brownish Almost all black1
Hairy Yes No1
Aggressiveness More aggressive Less aggressive1
Nesting Hives Paper nests in trees and shrubs1

Mexican Honey Wasp and Human Activity

Beekeeping and Citizen Science

Mexican honey wasps are mostly found in the southern regions such as Texas and Arizona. They can be found in citrus groves, where they benefit the ecosystem by pollinating citrus trees. In a suburban setting, they are generally not aggressive and often ignore human activity.

Citizen scientists and beekeepers can play a significant role in studying and protecting Mexican honey wasps. By observing these insects in their natural habitat, such as citrus groves, people can document their behavior and contribute valuable information to researchers.

Conservation and Impact on Ecosystems

Mexican honey wasps, classified as eusocial insects, display the following characteristics:

  • Build paper nests in trees and shrubs
  • Live in colonies with queens and workers
  • Pollinate a variety of plants, particularly citrus trees

Mexican honey wasps and their interaction with the Popoluca, Diaphorina citri, and human activity can greatly impact ecosystems. They help in pest control by being natural predators to Diaphorina citri, an invasive species that is harmful to citrus plants. By conserving and promoting the population of Mexican honey wasps, citizens can benefit ecosystems as a whole.

Table 1: Comparison of Mexican Honey Wasps and Honeybees

Feature Mexican Honey Wasp Honeybee
Body color Almost all black Yellow and black striped
Aggressiveness Not very aggressive Can be defensive when threatened
Interaction with humans Tolerant and often ignore human activity May potentially sting when disturbed
Habitat Trees and shrubs, especially citrus groves Various environments, including man-made structures

Mexican honey wasps not only serve as efficient pollinators but also contribute to the control of invasive pests. Their coexistence with humans is possible, given their non-aggressive nature. By continuing to study these insects and striving for conservation, we can better understand their role in ecosystems and promote effective collaboration between human activity and the natural world.

Safety and Precautions

Stingers and Aggressiveness

Mexican honey wasps, known for their almost all black body color, are relatively docile insects. They are part of the paper wasp family and usually are not aggressive toward humans. Unlike most wasps, they often ignore human activity around their paper nests, which are commonly found in the canopies of trees and shrubs.

Comparison table between Mexican honey wasps and typical wasps:

Feature Mexican Honey Wasps Typical Wasps
Aggressiveness Low High
Stinger Present Present
Nests Paper nests Various types
Location of nests Canopies of trees and shrubs Various places

Toxic Plants and Paper Wasp Nest Interaction

When interacting with Mexican honey wasp nests, it’s essential to be cautious with the surrounding environment. Keep an eye out for toxic plants, as they can be harmful to both humans and the wasps. Avoid touching or disturbing their nests, as it could potentially provoke the wasps and lead to an unwanted encounter.

Safe Consumption of Mexican Honey Wasp Honey

Mexican honey wasps produce honey that is safe for human consumption. The honey is stored within their beehives, which are made of paper-like material. It’s essential to ensure that the honey is collected using safe and sustainable methods to preserve the wasps’ habitat and maintain a healthy relationship with these beneficial insects.

Mexican Honey Wasp

Hi Bob,
This is a very exciting posting for us as it represents a new species for our site.  This is a Mexican Honey Wasp,
Brachygastra mellifica, and according to BugGuide:  “Larvae feed on honey (3), and probably also pollen; this is unusual for vespids.”  BugGuide also indicates the Mexican Honey Wasp is:  “Eusocial, that is, highly social, with worker and reproductive castes. More than one queen per hive, and there are females present with ovaries intermediate in size between workers and queens. Form large colonies by swarming (coordinated groups of queens and workers). Store honey, but do not cap cells, as do bees. Nests are perennial, built in low trees, with as many as 50,000 cells.”  BugGuide also states:  “One of the very few insects other than bees to produce and store honey.  Comment from Dr. Joan Strassmann, “They are docile a lot, but then they can explode, attacking en masse.

Mexican Honey Wasp

My neighbor has small kids and called a bug company that came and removed the nest. It was huge. Two-three feet tall and about a foot wide.
Thanks so much for the info!!
Thanks,
Bob Geissler

Hi Alejandra,
Our first impression was that this is a Paper Wasp in the subfamily Polistinae, but when we researched the Mexican Honey Wasp,
Brachygastra mellifica, on BugEric, we learned that it is a member of the Paper Wasp subfamily.  Your individual does appear to be a Mexican Honey Wasp.  We have some nice images of the nest of Mexican Honey Wasps in our archives.

Daniel ! Thank you very much for the information you share, it has been very helpful for our research.
