PREDATORS
Flowers are a whole ecosystem, so it is not surprising that where there is prey there are predators. You can watch drama worthy of the Serengety plains, albeit in tiny scale. The most common predators seem to be crab spiders, which are capable of changing color for camouflage depending on the flower they are using for hiding.

Crab spider on thistle
Crab spider on goldenrod, notice the adaptive coloration, quite different from the spider hiding on a thistle flower.
Crab spider and its prey, a solitary bee. Notice the two petals close together. These spiders join two petals with their silk for better hiding.
Another type of spider and its victim, a butterfly.
Ambush bug (Phymatidae), so called for obvious reasons. Notice the claws reminiscent of those of a praying mantis, although this creature is very tiny.
An ambush bug devouring a syrphid fly, probably Syrphus or Eupeodes
The Platidracus maculosus is a rove beetle or Staphylinidae. It feeds on other insects.
