1. What Are Robber Flies?
Robber flies, belonging to the family Asilidae, are a diverse group of predatory insects found worldwide. Known for their aggressive hunting tactics, they are also called assassin flies, reflecting their role as efficient killers of other insects. With nearly one thousand species in North America alone, as noted by entomologists, these flies exhibit a wide range of sizes, shapes, and colors. Their presence is a natural form of pest control, making them valuable members of various ecosystems.

2. Do Robber Flies Bite?
Do robber flies bite? While robber flies are equipped with a sharp, piercing proboscis, they primarily use it to stab and inject digestive enzymes into their insect prey. Typically, robber flies do not bite humans unless they feel threatened. A bite is rare, and it is generally a defensive reaction. Entomologists emphasize that these flies are more interested in hunting insects than biting people, so interactions are infrequent.
3. Why Robber Flies Don’t Typically Bite Humans
Robber flies usually don’t bite humans, focusing instead on their insect prey. Their primary interest lies in hunting and consuming other insects, which form their diet. Humans are not part of their food source, so there’s no incentive for them to bite us. Unless provoked or feeling threatened, robber flies generally ignore people, preferring to focus on their natural hunting behaviors.
4. Robber Flies as Beneficial Predators
Robber flies are highly beneficial predators in various ecosystems. They play a crucial role in controlling populations of other insects, including pests that can damage crops and gardens. By preying on a wide range of insects, robber flies help maintain ecological balance. Farmers and gardeners often appreciate their presence as a natural form of pest control, reducing the need for chemical interventions.
5. Identifying Robber Flies: Key Characteristics
How do you identify robber flies? Identifying robber flies involves looking for specific physical characteristics. These insects typically have a slender, elongated body with long legs adapted for grasping prey. One of their most distinctive features is the deep, concave area between their eyes. They also have a “bearded” face, with dense hairs around their mouthparts. These features help distinguish them from other types of flies, making them easily recognizable once you know what to look for.

6. Robber Fly Habitats: Where to Find Them
Robber flies can be found in a variety of habitats, from deserts and grasslands to forests and gardens. They prefer locations where they can easily hunt other insects. These flies often perch on the ground, rocks, tree trunks, or foliage, providing them with a vantage point to scan their surroundings. Look for them in sunny, open areas where insect activity is high, increasing your chances of spotting these skilled predators.
7. Robber Fly Hunting Behavior and Diet
What does a robber fly eat? Robber flies are aerial predators with specialized hunting behavior. They typically perch in a strategic location, waiting for unsuspecting insects to fly by. When an insect comes within range, the robber fly will launch itself into the air, intercepting its prey mid-flight. Their diet includes a wide variety of insects, such as flies, beetles, grasshoppers, and even dragonflies. Some species have specific food preferences, while others are generalists, consuming whatever they can catch.
8. The Robber Fly Bite: How They Subdue Their Prey
The robber fly bite is a crucial part of their predatory strategy. When a robber fly catches its prey, it uses its sharp proboscis to pierce the exoskeleton of the insect. The “necks” of insects and the open elytra of flying beetles are particularly vulnerable. Once the prey is impaled, the robber fly injects a combination of paralytic compounds and digestive enzymes. These enzymes quickly immobilize the prey and begin to liquefy its internal tissues. The fly then withdraws and consumes the resulting liquid meal.

9. Robber Fly Life Cycle: Larvae and Development
The robber fly life cycle includes both larval and adult stages, each with unique characteristics. Adult robber flies are commonly observed, but the larval stage remains somewhat mysterious. Robber fly larvae typically live in soil or decaying organic matter. They are known to be external parasites of beetle grubs and other insect larvae. The larvae feed on these insects, contributing to the control of soil-dwelling pests. Understanding their life cycle helps appreciate their role in the ecosystem.
10. Misconceptions About Robber Flies
One common misconception about robber flies is that they are harmful to humans. In reality, robber flies are generally harmless and are more interested in hunting other insects. They are often mistaken for other biting insects, leading to unnecessary fear. It’s important to recognize that robber flies are beneficial predators and play a vital role in maintaining ecological balance.
11. Robber Flies vs Other Biting Insects
How do robber flies compare to other biting insects? Robber flies are often confused with other insects that bite humans, such as mosquitoes, horse flies, and deer flies. However, there are key differences in their behavior and appearance. Mosquitoes and horse flies bite to feed on blood, while robber flies primarily feed on other insects. Unlike mosquitoes, robber flies are active hunters and do not typically seek out humans for food. Knowing these distinctions can help you correctly identify and appreciate robber flies for their beneficial role.
12. Benefits of Robber Flies in Your Garden
Robber flies offer several benefits to gardens by acting as natural pest control agents. They prey on various garden pests, including aphids, caterpillars, and other harmful insects. By reducing the population of these pests, robber flies help protect plants from damage. Their presence can minimize the need for chemical pesticides, promoting a healthier and more sustainable garden ecosystem.
13. How to Attract Robber Flies to Your Yard
Attracting robber flies to your yard involves creating a habitat that supports their needs. Provide open, sunny areas with plenty of perching spots, such as rocks, logs, and foliage. Avoid using broad-spectrum insecticides, which can harm robber flies and other beneficial insects. Planting a variety of flowering plants can attract other insects, providing a food source for the robber flies. A natural, pesticide-free environment will encourage robber flies to establish themselves in your yard.
14. Robber Flies and Aviation: An Unexpected Connection
What is the connection between robber flies and aviation? While seemingly unrelated, robber flies and aviation share an intriguing connection through the study of aerodynamics and insect flight. Entomologists and engineers have long been fascinated by the flight capabilities of insects, including robber flies. Their ability to intercept prey mid-air and execute complex maneuvers provides valuable insights into aerodynamic principles that can be applied to aircraft design. Studying insect flight helps improve aircraft efficiency and maneuverability, showcasing the unexpected ways nature can inspire innovation in aviation.
