Entomophobia, sometimes known as insectophobia, is a specific phobia characterized by an excessive or unrealistic fear (disgust) of one or more classes of insect, and classified as a phobia by the DSM-5.[1] More specific cases include katsaridaphobia (fear of cockroaches), melissophobia (fear of bees), myrmecophobia (fear of ants), and lepidopterophobia (fear of moths and butterflies). One book claims 6% of all US inhabitants have this phobia.[2]
Entomophobia may develop after the person has had a traumatic experience with the insect(s). It may develop early or later in life and is quite common among animal phobias. Typically, one has a fear of one specific type of insect. However, in some cases, this fear may encompass all organisms of the phylum Arthropoda. Entomophobia leads to behavioral changes: the person with entomophobia will avoid situations where they may encounter a specific type of insect. Cognitive behavioral therapy is considered an effective treatment.[1]
