class="dynamic">Introduction
This new hornet probably arrived with a assignment of imported pottery in November 2005 and,[link widoczny dla zalogowanych], afterward surviving the winter has scatter throughout many of Aquitaine. Its appearance was noticed almost swiftly,[link widoczny dla zalogowanych], and the spread to new areas is being well documented. Vespa velutina is not more perilous for humans than the European hornet (Vespa crabro), but it is considered a problem for honeybees in Asia. (N.B. This is NOT the Asian Giant Hornet Vespa mandarinia.)
This Asian Hornet is darker than the European, and almost hairy. The body of the European Hornet is basically wasp-like, a flat yellow with touches of black and brown.
Honeybees
All hornets will attack additional insect, but Vespa velutina is reported to attack hives of honeybees. They get cracking station and hover in front of the hive, capturing personnel for they depart and feeding them to their youth. In Asia they too enter the hives and cause solemn disruption, but it is thought that the devise of European beehives might give some conservation in France.
Identification
When two very alike species are base in the same area there is intense rivalry. Eventually one will replace the other. Both of these hornets are predators, especially of caterpillars, and they either like sugary fruits. The prune-growing region of Lot-et-Garonne is an ideal habitat and entomologists are carefully studying the result of this clash between the European and Asian hornets. (If you have any pertinent message you should contact Jean Haxaire: ).

It is unusual to ascertain a location favor this - where members of the common public can actively partake in scientific research without many expert learning. Most places where amateurs can assist require difficult identification (as in the case of the harlequin ladybird) alternatively expert collection techniques. With the hornets in France the situation is different. The added truth that there is honest care approximately the efficacy this new hornet might have aboard honeybees makes this a very worthy project to think. Anyone who vacations in South-West France and has a passing amuse in insects should certainly keep an eye out for these hornets.
This recently introduced category seems apt have been noticed very early, and since it namely a great insect which namely effortless apt look and no laborious to identify,[link widoczny dla zalogowanych], it provides a rare chance to study the dynamics of one invasion. Beekeepers are presumable to placard whichever hornets hovering nigh their hives, and workmen in the prune orchards will speck the lairs. In this way the reported sightings of amateurs tin be expected to give professional entomologists a very exact picture of future changes.
