Springtime Green—Our Most Popular Microscope Images for March 2022

Spring has arrived, and with it comes new life. The top microscope images for March have us thinking about the color green and how it represents growth, progress, and new beginnings. 

Staurastrum under the microscope

The star of the month is Staurastrum. In short, Staurastrum are single-celled green algae that can only be found in freshwater. The cell walls may be smooth or ornamented and contain compounds that make them resistant to decay. This specimen was found in Lake Mälaren in Stockholm, Sweden.

Bindweed leaf under the microscope

While this may not be a four-leaf clover, we got into the St. Patrick’s Day spirit with this stunning green image showing us the cellular surface of a bindweed leaf. While many of the bindweed species are invasive weeds, some are cultivated for their attractive, trumpet-shaped flowers, also known as morning glories.

Daphnia magna under the microscope

Karl Gaff takes two of the top five spots this month with his incredibly detailed images. We love this amazing capture of a Daphnia magna (a small planktonic crustacean) and her eggs. This species of Daphnia can produce a clutch of more than 100 eggs every three to four days until her death.

Arabidopsis thaliana pistil under the microscope

Here you're looking at an Arabidopsis thaliana pistil, the ovule producing part of this flower. Like the bindweed above, the thaliana is considered a weed. It is often seen growing along the side of the road in Europe, Asia, and Africa. This image is a composite of several focus-stacked DIC photographs and widefield autofluorescence microphotography (UV excitation). Tissues were cleared with chloral hydrate solution.

Daddy longlegs eyes under a microscope

Many people assume daddy longlegs are spiders, but they are actually arachnids like mites, ticks, and scorpions. They only have two eyes, as shown here peering at us, and can't make silk for spinning webs like spiders can.

Our bonus video features a tardigrade since everyone loves these microscopic animals. Tardigrades are also called water bears since their walk has been compared to a bear's gait and they prefer wet or humid environments. 

This poor water bear was caught off guard and had an “accident” on the slide when being filmed. Tardigrade accidents can be as large as 1/3 of their body size! The green coloring is caused by their diet of mainly algae and lichen.
