There doesnt seem to be a general definition for moss locust as it isnt a recognized term in botany or entomology. It could be a regional or colloquial name for a particular type of moss or locust, or possibly a misspelling or mishearing of related terms. However, without additional context, its hard to offer a precise definition. Its recommended to cross-check the term or refer to local guides or experts for clarity.
