Bee Assassin (Apiomerus crassipes)
Unlike many assassin bugs, Bee Assassins are good fliers. They also have sticky hairs on their front legs which help them secure their prey. It is probably for these reasons that the name "Bee Assassin" was bestowed upon them. They can capture bees while most other assassin bugs cannot. That does not mean Bee Assassin Bugs do not prey on other insects, however. In this case, I think the Bee Assassin is being an opportunistic scavenger. It is feeding upon a recently dead beetle up on our porch, a beetle perhaps stepped on during the previous night's activity under the porch light. The Bee Assassin avoided the beetle's hard shell by inserting its beak gap between head and thorax.
Once the beetle was punctured, salivary secretions were pumped through a canal inside the bug's piercing/sucking beak. The salivary secretions not only serve to quickly immobilize prey (in most cases) but they also dissolve the prey’s internal tissues. This process enables the assassin bug to withdraw the bodily contents of its prey.
