Reduviidae is a large, cosmopolitan family of predatory insects in the suborder Heteroptera. It includes assassin bugs (genera include Melanolestes, Psellipus, Rasahus, Reduvius, Rhiginia, Sinea, Triatoma, and Zelus), wheel bugs (Arilus cristatus), ambush bugs (genera include Apiomerus and Phymata), and thread-legged bugs (the subfamily Emesinae, including the genus Emesaya). There are about 7000 species altogether, making it one of the largest families in the Hemiptera.
Adult bugs often range from 4 to 40 mm. They most commonly have an elongated head with a distinct narrowed neck, long legs, and a prominent, segmented "beak" (proboscis). Most species are dark in color with hues of brown, black, red, or orange. The most distinctive feature of the family is that the tip of the proboscis fits into a groove in the prosternum, where it is rasped against ridges there to produce sound (a stridulitrum).
They use the long proboscis to inject a lethal saliva that liquefies the insides of the prey, which are then sucked out. The legs of some of these bugs are covered in tiny hairs that serve to make them sticky to hold onto their prey while they feed. The saliva is commonly effective at killing substantially larger prey than the bug itself. As nymphs, some species will cover and camouflage themselves with debris, or the remains of dead prey insects.

Hola Enio,
a superb macro of this bug from a nice point of view. Colours and sharpness are pretty good. Unfortunately, the narrow depth of field does not completely 'include' the legs. But this is only a minor point.
Best wishes, Peter

Great macro Enio, I like it.
Very good colors, contrast, DOF, POV, exposure, comp, and sharp details.
Well done!
Howard
