Briefly explain to a family member how flower spider coloration might evolve, and also why a flower spider that blends in with the flower is not an example of crypsis, which is defined as hiding (evolutionarily) from a predator.

The tendency of an animal that helps them from getting detected or observed by other animals is termed as crypsis. The phenomenon can be an antipredator adaptation or a predation strategy. Some of the modes of crypsis are nocturnality, camouflage, mimicry, and subterranean lifestyle.  

Flower spider is a species of spider that takes the color of the flower on which it hides. It is a predator, which works as an ambush killer, that is, it waits for the bees to come to the flower so that it can kill it. It is not an illustration of crypsis, the spider in the mentioned case is a predator, and is not hiding from anyone, it just makes it color to resemble the color of the flower so that it can kill its prey.  

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
