They are sieved from the manure, then dumped into a cement mixer, where they are dried and left to fall apart, resulting in a fine insect powder.
To distinguish whether a female mated with her brother or the unrelated male, we pierced the wing base of one male with a fine insect pin (hole diameter <0.5 mm on a wing measuring 15 mm) at least 20 h before the beginning of the observation period.
The seminal receptacle, spermatheca, and uterus were dissected out from the reproductive tract using fine insect pins.
After each trial, the female spermatheca and seminal receptacle were dissected using forceps and fine insect pins three hours after copulation.
Craniofacial cartilages were dissected with fine insect pins and were then flat-mounted for imaging on a Leica DM 2500 upright microscope using Leica software.
Cover the front of the fan completely with a length of fine, insect-proof, metal mesh.
U.S. Poet Laureate Robert Hass produced a new book of lyric poems, Sun Under Wood, including the beautifully luminous "Dragonflies Mating," with its images of "steam rising from the pond the color of smoky topaz" and "a pair of delicate, copper-red, needle-fine insects" mating "in the unopened crown of a Shasta daisy".
Regardless of adaptive fine-tuning, insect compound eyes are formed from ommatidia, each of which represents a functional unit that is composed of a highly conserved set of cells.
This proposed ecology suggests that visual specialisation to meet the demands of a fine-branch, insect grasping niche may have had a significant role in the early expansion of the primate brain [ 18, 23], a hypothesis consistent with recent evidence revealing an association between visual expansion and brain size in fossil endocasts of early primates [ 78].
Other researchers could easily overlook the insects' fine tunnels by digging too deeply or forcefully, says Juergens, who focused his efforts a few centimeters to tens of centimeters beneath the surface.
The pieces are so fine that small insects were included on the surfaces of some while others have what looks like bronze wires decorated around them.
