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.
