Summary

The tribe Larrini, within the family Crabronidae, includes a diverse array of square-headed wasps known for their ecological roles as pollinators and predators. With over 1,300 known species globally, they exhibit a wide range of habitats, feeding habits, and nesting behaviors.

Physical Characteristics

Larrini are characterized by their square-shaped heads and robust bodies. They typically have strong mandibles and varying color patterns, often exhibiting black and yellow or brown hues.

Identification Tips

Identification can often be made by observing the square shape of the head and the body structure. Additionally, the arrangement of the eyes and the presence of specific colorations can aid identification within the tribe.

Habitat

Larrini species inhabit a variety of environments, commonly found in sandy or open areas where they can dig burrows for nesting.

Distribution

The tribe Larrini is widely distributed, with over 1,300 species classified across 14 genera worldwide, and more than 160 species found in specific regions.

Diet

Larrini primarily feed on nectar and pollen from flowers, and many species are also predators, preying on other insects to provision their nests.

Life Cycle

Larrini undergo complete metamorphosis, which includes the egg, larval, pupal, and adult stages.

Reproduction

Females usually construct nests in the ground, where they lay eggs and provision them with prey for the developing larvae.

Predators

Natural predators can include larger insects, birds, and mammals that may feed on adult wasps or their larvae.

Ecosystem Role

As both pollinators and predators, Larrini play vital roles in ecosystems by aiding in plant reproduction and controlling insect populations.

Health Concerns

Some species may exhibit defensive behaviors and have stingers that can pose a risk of sting to humans; however, they are generally not aggressive unless provoked.

Collecting Methods

  • Net collection during flight
  • Malaise traps
  • Ground trapping techniques

Preservation Methods

  • Ethanol preservation
  • Pinned specimens
  • Collection in envelopes with proper labeling

Misconceptions

Many people confuse Larrini wasps with more aggressive species, as they tend to resemble social wasps; however, Larrini are primarily solitary and less likely to sting unprovoked.
