ROBBER FLIES Meaning and
Definition
-
Robber flies are a type of predatory insect belonging to the family Asilidae, known for their aggressive hunting behavior towards other insects. They are characterized by their large size, robust bodies, and long, strong legs. The term "robber flies" is derived from their habit of attacking and robbing other insects of their prey, engaging in opportunistic feeding.
These flies are renowned for their exceptional flying abilities, allowing them to actively pursue and capture their prey, often in mid-air. They have excellent vision, with large compound eyes that enable them to spot potential victims with precision. Robber flies possess a proboscis designed to inject venom into their prey, immobilizing it and liquefying its internal tissues. This venom, combined with powerful mandibles, facilitates their feeding process as they suck out the liquefied contents.
The diet of robber flies primarily consists of other insects, such as beetles, bees, wasps, butterflies, and various flying insects. They are known to be relentless predators, often overpowering prey that is significantly larger than themselves. Robber flies are therefore considered important beneficial insects in ecosystems, helping to control populations of potential pests.
In appearance, robber flies range in size from about ¾ inch to 2 inches, depending on the species. They often exhibit a variety of color patterns, including various combinations of black, gray, brown, and yellow, sometimes adorned with intricate markings.
Overall, robber flies are exceptional hunters that play a vital role in maintaining ecological balance by preying on other insects, showcasing remarkable predatory adaptations, and exhibiting a diverse array of species globally.
