North American Insects & Spiders

In re: AI
In the past few days, I have been using a paid version of ChatGPT to assist me in updating my site cirrusimage.com. It is unbelievably challenging, this LLM; it acts like a hyperactive, rambunctious teenager or, perhaps, a toddler jumping up and down next to you shouting suggestions and “solving problems” at a frenetic pace — it is impossible to get this thing to slow down and take one step at a time. Very very very frustrating. You tell it “do not do this” and it promises over and over again it will not but then promptly (in the very next exchange, nearly every single time!) do it. For a 72-year-old brain like mine, it’s fascinating. It makes mistakes – the same ones, over and over again. It never learns anything. It has memory of a sort, somewhere between gee I forgot and gee I forgot the thing you just said.
BUT! This machine has amused me, flattered me in a very effective way, and helped me rid my code of 15 years of google adsense nonsense, stray google analytics tags lurking in dark corners of HTML and css stylesheet elements and headers and footers, streamlined my css, and so much more — I’m thrilled.
HOWEVER, this kwazy wabbit manage to lead me into breaking my header, breaking the appearance of a google search engine that been in place for 1o years or more, and all sorts of other dangerous things. More things will get broken. –Ed
Spiders are the largest group of arachnids. They are easily recognized by their eight legs, and there are few creatures great or small that elicit such irrational fear in mankind. The vast majority of spiders are completely harmless. Spider Index
Hymenoptera: Bees, Wasps, & Ants belong to this large order, which also includes sawflies. Most species are solitary, but some, such as the domestic honeybee, exhibit a complex social structure in which exist sterile female workers and fertile male and female royalty.
Hymenoptera (Latin for “membrane wing”) is a vast assemblage of insects second only to Coleoptera (beetles) in the number of described species.
Rove Beetle Ontholestes cingulatus
Coleoptera: Beetles are the dominant form of life on earth: one of every five living species is a beetle. Coleoptera is the largest order in the animal kingdom. There are about 450,000 species of beetles, 30,000 of which live in North America. Beetles Index
Lepidoptera: Butterflies are revered for their brightly colored wings and pleasing association with fair weather and flowers. Lepidoptera comprises at least 125,000 known species including 12,000 in America north of Mexico. -Butterfly Index-
Skipper Butterflies might be one family that come as a surprise to many people. These speedy, feisty creatures will have you cheering for more!
Lepidoptera: Moths. Unlike butterflies, moths are usually nocturnal. Many moths and their caterpillars are major agricultural pests in large parts of the world. Moths Index-
Diptera: Flies are prevalent in virtually all habitats, with over 16,000 species in North America.
Flies are distinguished from all other insects in that they only have one pair of normal wings. Flies Index
Orthoptera: Grasshoppers, katydids and crickets have long, powerfully muscled hind legs that they use for jumping. Orthoptera Index
Hemiptera: True Bugs species number almost 5,000 in North America, and 40,000 worldwide. -Bugs Index-
Dictyoptera: Mantids and cockroaches. Mantids have triangular heads with huge compound eyes, and prominent forelegs, with strong mouthparts that can cut through even heavily armored insects. Both genders use their exquisite camouflage and ability to remain motionless to lie in wait and ambush unwary prey.
Neuroptera: Lacewings in this order have many veins and cross veins in their four transparent wings. There are only 338 species in North America.
The order includes lacewings, antlions, mantidflies, and spongilla flies.
Mayfly Adult
Ephemeroptera: Mayfly adults survive only a few hours or at most a few days. They eat nothing, nor do they crawl or walk. They only fly and mate, sometimes in swarms so large they show up on weather radar.
Rock Bristletail
Archaeognatha: Bristletails There are about 22 species of bristletail in 12 genera in 2 families in North America, with 350 species worldwide. Often confused with silverfish, bristletails are not found indoors.
Mecoptera – Scorpionflies, hangingflies and allies. Scorpionflies do not sting or bite. They spend most of their time hunting small soft-bodied insects or scavenging on fruit, dead insects and bird droppings.
Mecopterans have changed little from fossils 250 million years old, and entomologists consider now-extinct members of this order to be ancestors of modern flies, butterflies, and moths.
Classes Diplopoda (Millipedes) and Chilopoda (Centipedes)
Millipedes do not bite, pinch or sting, but may emit foul-smelling or irritating defensive chemicals.
The house centipede pictured here is considered harmless to humans or their pets. Size: Body = 25mm, overall = 7cm.
