Historically, less research has been conducted with invertebrates in Oklahoma relative to vertebrates. In recent years, though, ONHI has been collecting more records of invertebrates of various types found in Oklahoma. We have also been constructing an invertebrate database, which is now integrated into the Oklahoma Biodiversity Information System (OBIS).

Invertebrate data have been used by ONHI biologists for both basic natural history and applied research. Examples include:

• Freshwater mussels and general stream ecology
• Diatoms
• Aquatic macroinvertebrates
• Terrestrial snails
• Tiger beetles
• Robber flies
• Dragonflies
• Pollinator ecology
