How are the forelegs of Family Belostomatidae modified for predation?
Answer
Raptorial forelegs
The forelegs of insects belonging to the family Belostomatidae are highly specialized into strong, grasping appendages known as raptorial forelegs. This modification is directly related to their role as formidable aquatic predators. These legs function similarly to those found on a praying mantis, providing the necessary strength and grip to effectively seize and hold slippery prey items such as small fish or tadpoles while the insect administers its bite. This structure is one of the key identifying features differentiating them from many other aquatic insects that might possess swimming or rowing appendages instead.
