This species is a sit-and-wait predator that captures pollinators as they visit the inflorescences on which the spider sits.

[2] Males search for sedentary females within a heterogeneous habitat and guard them until they are sexually mature to reproduce.

[6] Female M. formosipes are able to change their color between yellow and white to better match the flower they are occupying.

Male M. formosipes are nectarivores and get a majority of their nutrients from consuming nectar from Daucus carota , commonly known as Queen Anne's Lace.

Since the male M. formosipes are significantly smaller than the females, they are able to benefit from the low amounts of sucrose found in nectar.

[10] The female crab spider will deposit their eggs into a silk sack roughly 10-14mm wide on nearby foliage.

[11] The sexual dimorphism of the white banded crab spider has resulted in significantly smaller males from females.

Males will travel by jumping from one plant part to another as well as traversing across a string of silk they throw into the wind that stick to an object.

[12] Male M. formosipes spend a significant amount of time searching for unmated penultimate females.
