| 説明 | Citizen scientists identify 47 different dragonflies and damselflies in the Cascade-Siskiyou National Monument, Aug. 3, 2019.Several of the insects discovered during the BioBlitz event last weekend were previously unknown to live in the southwest Oregon national monument. Dragonflies and damselflies are carnivorous insects in the odonata family, an ancient classification with fossil records going back 325 million years. Scientists think as many as 60 different species of dragonflies and damselflies live within the Cascade-Siskiyou National Monument, an area specifically protected for its tremendous biodiversity. Previous BioBlitz events, coordinated with the local friends group for the monument, have focused on butterflies, fungi, reptiles and amphibians, and birds. 📍 Visit the national monument: on.doi.gov/2E7cv7X Photo/video archive: goo.gl/FX1Bk1🌐 #360video: goo.gl/bFkJhaBLM photos: Joel Brumm and Christine Beekman |
