[{"text_idx": "#000004", "text": "Asian hornet (Vespa Velutina) is a particular threat to honey bees, unlike our own European hornet (Vespa Crabro). The Asian hornet is slightly smaller than its native counterpart, with adult workers measuring from 25mm in length and queens measuring 30mm. They have a mostly dark brown or black velvety body except for the fourth abdominal segment which is a conspicuous yellow band near to the rear. The brown legs have yellow ends, which is why it is often called the yellow legged hornet, while its face is orange with two brownish red compound eyes."}, {"text_idx": "#000005", "text": "When predating on honey bees, hornets can be seen hovering outside a hive entrance, waiting for returning foragers, this is the characteristic \u201chawking\u201d behaviour.
