There is a small wetland area out at the arboretum known as The Seeps. I was out there the other day, and I came across all of these small creatures dancing around in the sunlight that was breaking through the clouds. They were in this patch of bracken ferns that were sprouting up and beginning to unfurl. Periodically they would land and deposit eggs. I don’t know if they were laying the eggs on the fronds or piercing part of the plant and laying them inside. Trying to capture a photo was a little challenging. They are sensitive to movement, and they are small. After awhile I managed to take a couple of photos. A knowledgeable friend of mine identified them as sawflies. I found a photo of the species Strongylogaster distans Norton, and it seemed like a good match.
Observing these small creatures reminded me that there is an entire world occurring mostly unnoticed. Reading on the website of the Smithsonian, it says that there are some 900,000 different kinds of living insects known in the world (approx. 91,000 in the United States). It is estimated that there are somewhere between 2 - 30 million yet to be discovered. Additionally, insects probably have the largest biomass of the terrestrial animals. Apparently it has been calculated that “at any time, it is estimated that there are some 10 quintillion (10,000,000,000,000,000,000) individual insects alive.” This is blowing my mind.
Read this brief article published on the Smithsonian’s website. It’s awesome.
