[1][2] M. celer are sit-and-wait predators who hide out on the flowers and upper stalks of plants, waiting for prey to pass by.

The spider is a notable example of a species that displays sexual size dimorphism (SSD),[4] a phenomenon in which one sex is significantly larger than the other.

[5] Like other spiders within the Thomisidae family, M. celer are an important pest control species for agriculture since they hunt at the upper parts of crop plants where the grains or other harvested products grow.

[1][6] Several older website and journal entries about the spider can still be found under the species name Misumenops celer, as with several of the references used in this article.

[3] Adults show sexual dimorphism not only in size but in color, and mature males are often darker than females and have distinctive red bands on their legs.

[3] M. celer is a nearctic spider species distributed widely across the North American continent (see the purple area in the map below).

The exact selection pressures that have resulted in such dramatic size difference between the sexes in this species are still not well-known, and according to research, it does not appear that female-biased SSD in M. celer has evolved for any commonly acknowledged pre- or post-copulatory survival benefits to the male or female.

[4] Experiments have shown that virgin females will almost always accept the first male mate that comes along, showing no preference for smaller size or any other particular trait.

Members of the Thomisidae, as well as Salticidae, Argiopidae, and Oxiopidae spider families, have been shown to feed mainly in the upper part or head of the sorghum crop, where the grain is produced.

[5] Because sorghum is grown for the grain it produces, M. celer and other Thomisids provide important protection for farmers against the destruction of the crop's value.
