Class: Insecta
Order: Lepidoptera
Family: Lycaenidae
Tribe: Polyommatini
Genus: Polyommatus
Species: P. icarus
Binomial name
Polyommatus icarus
Habitat: The common Blue is widespread and common.
It is double brooded.
Larval Food Plant: Bird's-foot-trefoil Lotus corniculatus
Flight Time: Mid-May to mid-August/September
Hibernation: Overwinters as a larva.
The upperwings of the male Common Blue are a pale violet-blue with a silvery-blue colour towards the body.
The upperwings of the female varies from brown to deep violet-blue and have a series of black-bordered orange cresent shaped marks at the outer margins.
Both sexes have a distinctive clear white fringe.
The underside of the male is grey with a silvery-blue at the base which is more marked on the hindwings. There are a series of white-ringed black spots followed by a series of orange spots at the outer margins. There are similar white-bordered black spots and a white-bordered black bar more medially.
The ground colour of the female's underwings are brown and slightly bolder in colour than the males, often with more well developed orange spots, which are larger and more pronounced.
Life Cycle of the Common Blue
Ovum:
The small white disc shaped eggs, measuring up to 0.6 mm in diameter, are laid singly on the young terminal
leaflets of Bird's-foot-trefoil and other leguminous food plants, and hatch in c.9 days.
Larva:
The fairly stout larva measures up to 13 mm in length, tapers towards the extremities and is flattened
towards the sides. The body is green with a darker green mediodorsal line and whitish lateral stripe below
the level of the white spiracles. The small glossy head can retract into the body. The setae are light brown
dorsally and white laterally. On the upper surface of the 10th segment there is a honey gland.
The larva feeds on its food plant by day and the first generation is fully grown in about 6 weeks and
goes on to pupate. But those of the second generation overwinter , probably in their third instar, about
late Septrmber/early October. They hibernate low down on the stem of the food plant or on leaf litter.
It is often seen tended by ants who are attracted by its honey-like secretions, a feature seen in other members
of the Lycaenidae family. Feeding is resumed late March or early April of the following spring.
Pupa:
Pupation of the overwintering larva occurs about April but later in summer for the following generation(s).
This occurs at the base of the food plant or sometimes on its lower stem under a few strands of silk.
Some are buried by ants and it may occasionally be seen inside an ant's nest under a stone.
The pupal stage lasts c. 14 days.
Adult:
The adult is on the wing by mid-May to early July and again in late July to early September and
later for further generations.
Jumping spider (family Salticidae), Jumping spider (Salticus scenicus) [Credit: M.W.F. Tweedie—Natural History Photographic Agency/EB Inc.]any of more than 5,000 species of spiders (order Araneida) known for their ability to jump and pounce upon their prey. They range in size from 2 to 22 mm (0.08 to 0.87 inch), although most are small to medium-sized. They are very common in the tropics, but some also live in northern and even Arctic regions. Though there are a few species that have hairy bodies, most species have few hairs (setae). The body is often brightly coloured or strikingly patterned. Jumping spiders have keen vision for spiders and are active during the day in sunny areas.
The hairs on tarantulas, known as setae, are extremely sensitive and can detect the slightest changes in air pressure. This can help them not only to sense predators and prey, but also changes in weather patterns. This one was walking across the road just a few minutes before a rainstorm and was likely moving in response to the changing weather.
Otero County, CO
Large Scutellinia on very wet rotten wood.
The spores measure 22-24X15-16u. and have large warts which sometine coalesce to form partial nets.
Setae variable in length but can reach up to about 1.5mm in length. and have a multifurcate base.
Not sure of my identification, as I am not certain if my microscope have a suffisent resolution to properly the spore ornamentation
This fall I was moseying in with the dog and found this large creature by the garage. Photo material! He/she wasn't very interested in letting me take his/her picture. These will have to do.
The little hairs are called setae, and apparently I shouldn't have touched this as they can break off and cause a rash.

Braved the weather today and went back to see if I could find more Allacma fusca's, well it turns out that yesterday's find was a wrongly identified by me, should always listen to Frans LOL. I found loads of these small pink Sminthurinae, this is Caprainea marginata and is one of the prettiest Globular Springtails I have found to date, a pink Springtail with wonderful vivid ocelli. Now interesting information below, this is a rare find, it has only been found at 2 other UK sites, the info below is from the Roehampton Collembola site :-
ws1.roehampton.ac.uk/collembola/taxonomy/index.html
Caprainea marginata (formerly called Sminthurus marginatus) is rare. It is only known from two sites, Vigo Cave in the west of Ireland and Keston Common, Kent. The species is pink or pale rusty brown in colour and reaches a length of 1.4 mm. The fourth antennal segment (ant4) is divided into 15 subsegments. Some setae on the third antennal segment (ant3) are longer than others. Both edges of the mucro are serrated. The female sub-anal appendages (SAA) are feathered at the tip. The empodium of the foot is about the same length as the claw.
Hope everyone has a great weekend, I'm sure it is going to rain, so be prepared, I wasn't fully prepared and got soaked today LOL :o)
VIEW ON BLACK
Showing a bright‑green moth larva whose cylindrical body is dotted with pale‑yellow pinacula sprouting fine hairs, bears three pairs of true legs just behind the head and several hooked prolegs to cling tight to the stem; its uniform colour, yellow spiracles and halo of setae camouflage it among foliage before it pupates.
A. soror is a very large scoliid wasp reaching up to 3 cm long. The body is black, and the wings are smoky with a blue iridescence.[2] This colour scheme is shared by several other Australian scoliids. The setae of A. soror are entirely black, and the second sternite is non-tuberculate.[3] As a member of Austroscolia, the wings have a single recurrent vein and three submarginal cells.[4]
Distinguishing this species requires close and thorough inspection of specimens. The allied and mostly sympatric A. nitida varifrons has denser punctures on the pronotum, mesothorax, and gaster.[5] A. commixta of the Northern Territory, known only from the male, has a tuberculate second sternite and has shorter antennae. Another common species, Australelis anthracina, has two recurrent veins and white setae.[6] While most females and southwestern males of that species are entirely black, males in the east have a single pair of yellow to orange spots on the third segment of the gaster.

The final section of vein R1 has several setae on its ventral surface (in contrast to A. pilipennis where there are usually none).

Photographing the stuffing out of every Sedgesitter that I see pays off here, I think. Note the black comb on the mesofemur and long black setae on the profemur.

About 13 mm long.
The following information is from www.knowyourinsects.org at www.knowyourinsects.org/Hemiptera1.html#Largus%20cinctus_TL .
Largus cinctus (no specific common name), subfamily Larginae, family Largidae.
□ Several species of bordered plant bugs look alike, but size and location can help to narrow down the identification. This one was photographed west of the Rocky Mountains in the U.S., and had a body length of about a half inch (13 mm), which suggests it is the species Largus cinctus. Click on the photos to zoom in and see the bit of red color at the base of the antennae and the fine setae (insect “hairs”) on its body.
□ Other species in the genus Largus include Largus californicus, which is also found in the same area (California), but it has a body length almost twice that of Largus cinctus; and Largus succinctus, which is the same size as Largus cinctus, but is more common east of the Rocky Mountains.
Thomas says, “Another one I found on a walk and trapped with my ‘Bug Bottle,’ which I now always carry with me.”
The larvae are elongate and have large sickle-shaped
mandibles. They are active, but sluggish and soft
bodied, with tubercles (raised bumps) and long setae
(hair). They are commonly called aphid lions and
feed. on aphids, other small insects and eggs.
Unfortunately, I did not take notes on setae, clitellum, or the location of male pores so the identification is uncertain. It does resemble Lumbricus rubellus.
Found under paving sones between house and garden.

This is the only British Actia species that lacks dorsal setae along vein Cu. The dorsal setae of R1 are short and confined to the apical third.
Here are 10 interesting facts about the puss caterpillar (also known as the Southern Flannel Moth larva or asp):
1. Venomous Spines:
Despite its soft, furry appearance, the puss caterpillar is covered in venomous spines hidden beneath its hair-like setae.
2. Painful Sting:
Contact with the spines can cause immediate, intense, throbbing pain, often compared to a bee sting, and can lead to burning, itching, rashes, swelling, and even blisters.
3. Variable Reactions:
The severity of the reaction to a puss caterpillar sting can vary significantly among individuals, ranging from minor irritation to severe systemic reactions.
4. Most Venomous U.S. Caterpillar:
It is considered one of the most venomous caterpillars in the United States, particularly common in areas like Texas.
5. Resemblance to a Cat:
Its common name, "puss caterpillar," likely comes from its resemblance to a fluffy cat due to its dense, fur-like covering.
6. Adult Form:
The puss caterpillar is the larval stage of the Southern Flannel Moth (Megalopyge opercularis), a soft, fuzzy moth native to North and South America.
7. Other Names:
It is also known by various other names, including asp, possum bug, woolly slug, and perrito (Spanish for little dog).
8. Increasing Toxicity with Size:
The toxicity of the venom and the intensity of the pain from a sting increase as the caterpillar grows larger.
9. Defense Mechanism:
The hair and hidden spines serve as a potent defense mechanism against predators.
10. Emergency Care:
If stung, it is recommended to apply adhesive tape to the affected area and strip it off repeatedly to remove embedded spines, and seek medical attention if severe reactions occur.
