Mimicry
Most mimicry can be qualified as defensive. Generally a mimic will choose a model which advertises via aposematism (see below) in order to signal its unpalatability. More contentious is the idea of offensive mimicry in which a mimic chooses its prey as its model in order to approach and engineer a situation that puts it at an advantage as a predator of said model.

Bee-mimicking assassin bug (Apiomerus sp.) with prey is an example of such mimicry. However, as is often the case, the waters are muddied by the model's own defences, a painful sting.



Aposematism (Warning colouration) can be used in mimicry, or to to indicate an organism's own toxicity

Braconid wasp ovipositing into a fallen tree trunk. After searching for beetle larvae using chemical and proprioceptive cues, the ovipositor which is several cms long drills into the trunk and inserts the eggs into its host.



Megalopygid caterpillar (Bayucca sp.). The long hairs conceal painful spines, delicate and ready to break off and imbed in the skin at the slightest pressure:



Thanks for looking and commenting,

Thanks everyone, much appreciated.

Samureye- lots of experience, but also there are some giveaways, slight movements, common places where they'd normally hide themselves, and it can be much easier at night when they're not hiding from keen eyed predators, but rather from those using chemosensory and touch senses.

Paul,

An excellent set.

I see that Selenops means looks like the moon but refers to the crescent arrangement of the eyes.
