Definition
Noun: 1. A species of moth: The gypsy moth (Lymantria dispar) is a moth native to Europe and Asia that was accidentally introduced to North America. Its caterpillars are highly destructive leaf-eaters, considered a major pest of many deciduous trees, including oaks and maples.
Usage Examples
- Noun:
- The gypsy moth infestation has defoliated thousands of acres of forest this summer.
- Scientists are studying biological controls to manage the spread of the gypsy moth.
- Many communities have quarantine measures to prevent the movement of gypsy moth egg masses.
Advanced Usage
- The term is sometimes used metonymically to refer to the infestation or the damage caused by the insect, not just the insect itself.
- The region is battling gypsy moth for the third consecutive year. (Here, "gypsy moth" refers to the ongoing infestation problem.)
Variants and Related Words
- Lymantria dispar (n): The scientific, Latin name for the gypsy moth. This term is increasingly used in formal and scientific contexts.
- Spongy moth (n): An adopted common name replacing "gypsy moth," as the latter is considered an ethnic slur. Official organizations now promote this new name.
- Gypsy moth caterpillar (n): Specifically refers to the larval stage of the insect, which is the life stage that causes the actual defoliation.
Synonyms
- Spongy moth (n): The new common name.
- Lymantria dispar (n): The scientific name.
Notes on Usage
- Important Note: The common name "gypsy moth" is derived from an ethnic slur against the Romani people. Its use is now widely considered offensive. In formal, scientific, and increasingly in public communications, the name "spongy moth" is the preferred and recommended term. The example sentences above use "gypsy moth" strictly to define the historical and still-recognized term, but learners should adopt the non-offensive alternative "spongy moth" in their own usage.
Noun
- European moth introduced into North America; a serious pest of shade trees
