Eclectic Perambulations in the Noosphere
Researchers have studied these “diamonds” since the weevil’s discovery in the early 19th century but, until recently, no one knew know how the scales reflected so much light."
"The Strand Magazine ran an alarming feature in 1910: “If Insects Were Bigger.” The editors inserted photographs of ordinary English insects into contemporary Edwardian street scenes, with pretty terrifying results. “What a terrible calamity, what a stupefying circumstance, if mosquitoes were the size of camels, and a herd of wild slugs the size of elephants invaded our gardens and had to be shot with rifles!”"
"Thrips are tiny insects, typically just a millimetre in length. Some are barely half that size. If that’s how big the adults are, imagine how small a thrips’ egg must be. Now, consider that there are insects that lay their eggs inside the egg of a thrips.
That’s one of them in the image above – the wasp, Megaphragma mymaripenne. It’s pictured next to a Paramecium and an amoeba at the same scale. Even though both these creatures are made up of a single cell, the wasp – complete with eyes, brain, wings, muscles, guts and genitals – is actually smaller. At just 200 micrometres (a fifth of a millimetre), this wasp is the third smallest insect alive* and a miracle of miniaturisation."
Kudzu is an amazingly prolific invasive plant that has been devastating large areas of farmland, fields, and woods in the southern United States. When it first arrived, it spread uncontrollably because it had no natural enemies. Now, one has been found - a beetle that arrived as another accidental immigrant.
But the new arrival is a mixed blessing, because it also eats other legumes, including soybeans. This video was prepared by entomologists at the University of Georgia College of Agricultural and Environmental Science.

"The locust borer beetle is native to North America. It attacks only black locust trees of the genus Robinia, which originally grew only in the Allegheny and Ozark mountain regions. Due to its ability to thrive in poor soils, the black locust has been widely used as a shade tree and in reclaiming land damaged by farming and strip mining. The locust borer beetle has extended its range as a result. It is now found over most of the U.S. and southern Canada. This is one magnificent insect - about 1" long, stately and impressive. I'd never seen one before I stumbled across this guy. The whole time I was shooting, I was saying, "What the hell is this thing!? What a COOL bug!" (Yes, I frequently talk to myself and my subjects when photographing them. Passersby must think me crazy).
Locust borer larvae tunnel into a tree's trunk and branches, weakening the tree and making it susceptible to wind breakage. The damage from borer tunneling and wind breakage often results in deformed trees or clumps of sprout growth."
"The acorn weevil, Curculio, is one of the weevils that infest hardwood nuts. These weevils attack both red and white oaks and are found wherever the hosts grow. These live adult weevils were found in a large grove of Butternut, Shagbark Hickories and Oak trees at the original site of the Native American burial mounds at Winfield, IL USA.
Acorn weevils have snouts with small, saw-like teeth at the very end. There are two types, or genera: the long-snouted acorn weevils (genus Curculio) and the short-snouted ones (genus Conotrachelus). The longsnouted acorn weevil's snout may be equal to or greater than the length of its body. These specimens are, of course, the long-snouted variety.
Adults of both genera feed on acorns, but only the long snouted weevils can drill into the shells to feed and lay eggs inside the nutmeat. The tip of the snouth is actually a miniature saw, and the weevil places the tip against the shell, circling endlessly around the pivot point until the shell is pierced. Females place eggs inside the nut using a long ovipositor that descends from the abdomen..."
