"It is likely that every tomato you eat was pollinated by a bumble bee... [Their anthers] will only release their pollen when they are vibrated at a frequency of around 400 Hertz, and bumble bees do this by grabbing hold of the anthers and vibrating their flight muscles." - McGavin, The Hidden World

It's folded in half diagonally and resting on a wood and metal bench as a backdrop.Photo of an enamel pin of a celestial-themed bumblebee. The bee is facing right in a rounded pose with wings sticking out above it. It has a large round eye and sparkles on the body with constellation-like patterns as the wing veins. The antennae and some of the legs are mostly depicted by gold metal. The pin is resting on a blue cloth surface with some round gold accents. Mark at the bottom of the image reads "shop.mothmonar.ch"Photo of two vinyl stickers of stylized millipedes posed to resemble infinity symbols. Both have metallic color areas for their legs and between their black body segments - the top is rainbow, the bottom is red. They are on a brown-grey background. Text reads "Shop.Mothmonar.ch"Photo of a lavender sticker sheet with whimsical celestial-themed moths and related accent stickers. Nine moths have moons, stars, and small constellations on their wings with purple, blue, and pink palettes. Their shapes are inspired by real species like the luna moth, comet moth, cecropia moth, sphinx moth, etc. Accent stickers include four-pointed stars, five-pointed stars, a moon, a planet with a ring, and a four-pointed comet as well as a line of moon phases vertically in the middle of the sheet. Some of the stars, moons, and markings have metallic details catching the light here. The top of the sheet reads "Magic Moon Moths" and the bottom has the artist's name, "Moth Monarch".

The elephant mosquito (Toxorhynchites rutilus) is one of the largest mosquitoes in North America with a wingspan of 12mm! They also do not bite, as females do not use blood for their eggs. They're also predators of disease-causing mosquitoes like those in the genus Aedes. So, friends! #invertefest

I just saw a glitch in the matrix. I put a bowl on the kitchen counter and dropped a handful of kibble in from a few inches up. One kibble rebounded up two feet to the height my eyes and landed behind the sink. That kibble had more kinetic energy than the potential energy of its drop would provide.

Panel 01: A ball drawn on a whiteboard. The ball has two eyes on its "sides", the sides not facing you. A wooden teaching pointer is pointed at it, and someone is speaking from off-panel, saying "prey animals have eyes on the SIDES of their head, like this."

Panel 02: The teaching point now points to another part of the whiteboard, where a ball has two eyes on its front. The off-panel speaker says "predator animals have eyes on the FRONT, like THIS."

Panel 03: We zoom out and reveal the speaker to be Shen, who is holding the teaching pointer and asking the class ahead of him, "any questions?"

Insect hemolymph does not supply the insect with O2. Instead, trachea branch from spiracles to provide O2 to the proximity of every cell. During development, cells deficient in oxygen release the signal protein FGF to draw the forming trachea nearby. (Alberts et al., Molec Bio of the Cell, 7th ed)

A fertilized insect egg doesn't repeatedly divide like a vertebrate egg. Instead, its nucleus duplicates itself thousands of times (6000 in fruit flies). These nuclei migrate to the cell periphery, where the membrane folds around them to form cells. (Alberts et al., Molec Bio of the Cell, 7th ed)

This digitally painted piece honors the survivor spirit of the coyote by tracing its lineage from the first cells of life to the animal trotting our landscapes today. Below the horizon, carefully chosen ancestors mark pivotal moments in adaptation, each contributing to the form and survivor we see today. Above the horizon, Coyote stands alert at the center, framed by both Denver’s skyline and a mountain backdrop, symbols of their ability to thrive in cities as well as wilderness. Embedded in the ground are the skulls and bones of carnivores whose lineages ended long ago, emphasizing Coyote’s persistence in contrast.

DNA nucleotides appear to average a mutation rate ranging from 1 to 3 out of every 10 billion copied. This likely restricts organisms to having at most 30,000 genes that are "essential," placing an upper limit on the complexity of organisms. (Alberts et al., Molecular Biology of the Cell, 7th ed.)

This web has been on my car for about 3 weeks now, surviving all my driving, including once for 2 miles at 60 mph. It sometimes catches small flies at slow speeds. The spider stays behind the mirror during the day. I visited at 4am once to try to ID, but I wasn't sure. Maybe a young Neoscona.
An orb web spritzed with water to make it visible, attached at the high end to the outside of the driver's side mirror, at the other end on the door just below the window, and below lower on the door. The spider is not visible because it is a daytime shot.

Moth populations are declining and one concrete thing you can do to help is turn off your outdoor lights at night OR switch to “bug bulbs” (yellow LEDs) that don’t disrupt their lives.
