Most species of the entomophthorales are pathogens of insects. A few attack nematodes, mites, and tardigrades, and some (particularly species of the genus Conidiobolus) are free-living saprotrophs.
The name "entomophthorales" is derived from the Ancient Greek for insect destroyer (entomo- = referring to insects, and phthor = "destruction"). Named after genus Entomophthora in 1856.

Biology
Most species of the entomophthorales produce ballistic asexual spores that are forcibly discharged. When not landing on a suitable host, these spores can germinate to make one of several alternate spore forms, including a smaller version of the original spore, or (in some species) an adhesive spore elevated on a very slender conidiophore called a capilliconidiophore.
Classification
Debates have centred on whether the Basidiobolaceae should be included in the entomophthorales, or raised to ordinal status. Molecular systematics approaches so far give an ambiguous answer. Some analyses suggest the Basidiobolaceae are more closely related to certain chytrid fungi than to the entomophthorales. and place it within the Chytridiales order. Others find weak support to maintain them in the Entomophthorales. Morphological characters can be found to support either hypothesis.
