The environmental databases will have some insect items, e.g. Environment Abstracts lists 84 items under the subject heading butterflies, but this list will be less comprehensive. This database will index on peer-reviewed scientific academic journals. Common names are not subjects in Ecology Abstracts. Indexes 225 key journals in this field. This database may use the taxonomic name, but usually indexes under the common name.
Subject headings can be inconsistent.
Because there is no abstract, usually just searching on the common name or taxonomic name will find most articles. Do limit by language. Starred items in Environment Abstracts are full-text in our library. Florida's Cooperative Extension provides brief descriptions of individual species of beneficial insects, usually accompanied by a number of photographs. Some are of individual families and species and their life cycles.
