Dragonflies hunting skills are unique,being based on predictive tactics as opposed to many other insects hunting in a reactive way, a new study reveals. The findings of the inquiry disclosed that the insect has a personal approach to catching its prey and is not contingent to the prey’s motion.
A group of researchers from Hughes Medical Institute in Ashburn, Virginia were curious to find out more information about tactics of dragonflies while chasing their future victims.
The researchers found that dragonflies make use of a one of a kind chasing technique, a perceptive technique and not a responsive pattern of behavior. The scientists used a manufactured fly to pull the dragonfly into the chase and observed the whole process with ultra-high velocity cams.
This predictive way of action implies that the dragonflies utilize an interesting chasing technique when drawing close to their prey and don’t simply duplicate the motions of their next meals.
Up to this point, specialists suspected that just mammals, fish and some birds practice predictive hunting. Even more, they suspected that dragonflies simply fly around their prey indiscriminately like bees and flies and reproduce their motion until they are sure they can get up to speed with the hunted.
This new study has demonstrated the scientists were wrong to jump to such conclusions. Apparently, these lovely little insects have personalized in a unique manner their hunting rituals. Actually, these small insects are like tricksters when hunting, with camouflaged moves and body orientation, but always with an eye on their prey.
Researchers have said that if the dragonflies used responsive chasing patterns, each dynamic of their prey would have been replicated precisely the same by the bug. In the case of the fake fly, even if the fly changed its direction, the dragon fly did not proceed to replicate this change about 70% of the time.
Moreover, since 75% of the dragonflies movements were not the same as those of the hunted fly , scientists assume that dragonflies may even be capable of planning their hunt.
Anthony Leonardo, a researcher that was a member of the investigation group, said that the bug adjusts its body but the dragonfly outwardly keeps bolting on its target. By utilizing this system, the ‘creepy crawly’ is equipped for getting the prey from behind and underneath, two of the blind sides of the prey.
Leonardo and his group soon want to inspect how the neurons in the dragonfly are used while hunting and how they send the right message to muscles in order to help the dragonflies alter their flight course so abruptly.
