Excerpt from Wikipedia:
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. Currently, 1,010 species have been identified. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
I'm looking for details ... :-)

Black Jezebel
Delias nigrina FABRICIUS, 1775
Family - PIERIDAE
subfamily - PIERINAE
Tribe - PIERINI
Introduction: There are about 225 described species in the genus Delias. The butterflies are popularly known as Jezebels. Most species are white or greyish on the upperside, with blackish margins and apexes. On the underside they are gaudily patterned in red, yellow, black and white - the colours serving to advertise their unpalateable nature to would-be predators. Many of the species are highly localised, being endemic to particular islands in south-east Asia, or restricted to certain mountain ranges, e.g. in New Guinea. Others occupy much broader ecological niches, and are more generally distributed. Delias nigrina is found along the eastern side of the Great Dividing Range in Queensland, New South Wales and Victoria.
Habitats: This species inhabits open forested areas at elevations between sea level and about 1000m.
Lifecycle: The eggs are yellow and laid in clusters on leaves of the foodplants. The caterpillars are dark green with 2 dorsal rows of yellow spots, from which arise long white setae. They feed gregariously on the foliage of mistletoes Amyema, Dendrophthoe and Muellerina ( Loranthaceae ). The pupa is glossy orange with long black curved spines, and long white head horns, giving the impression of a fungal growth. It is attached to the upper surface of a leaf, on the midrib, and attached by the cremaster and a silken girdle.
Adult behaviour: Males can sometimes be found imbibing moisture at the edges of streams. Both sexes very mobile and are more often seen in flight then settled. They tend to pause for a few seconds to nectar at a flowering bush, strongly favouring Lantana, and often visit several plants within a small area before moving elsewhere.

A shot for Frans Janssens :-)
this is the best shot from the setae on the small abdomen until now, I even don't know if it is a male...
I saved yesterday a dozen of Bourletiella hortensis from the lawn mower...perhaps also a male...
The crested gecko has hair-like projections found above the eyes, resembling eyelashes. It has a wedge-shaped head and a crest that runs from each eye to the tail. Crested geckos do not have eyelids and so they use their long tongues to moisten their eyes and remove debris. The toes and the tip of the semi-prehensile tail are covered in small hairs called setae.
Ommatius coeraebus
Family: Asilidae
Order: Diptera
There are 17 known species of the genus Ommatius, the plume tops, in Australia. Although a couple have some similarities, only coeraebus is recorded in south NSW.
Note the "beard" of setae around the face, neck and rostrum. It is believed that these setae provide some protection from damage by their prey.
They are active predators, mainly of flying insects, and they appear to be unselective in prey species. Their prey does include members of their own species, often with a female predating a smaller male that attempted to mate. Their long legs can be used to capture other insects in flight.

I think conjuncta, but is the only way to distinguish monticola the altitude ? But from how much meters ? Here 300m.

In this case, the prey is small Crane Fly. The prey has been pierced with the rostrum, allowing the Robber Fly to inject it with a cocktail of proteolytic enzymes and neurotoxins. The liquified contents of the fly will then be sucked up through the rostrum.
The cocktail of toxins include molecules that have not been found elsewhere, indicating that Asilidae toxins emerged from a unique evolutionary pathway
(Drukewitz et al, 2018).
The two insects have been recorded in separate iNaturalist observations:

I photographed the same species 20 kilometres away predating on a small Thynnid wasp:

This female Ringlet has an egg, clearly visible, at the end of her abdomen. Ringlets, like Marbled White, lay eggs in flight over grassland so this egg will be dropped when she next takes flight unless it is a laid egg which has somehow remained attached to the 'setae' at the end of the abdomen. My thanks to Tim Melling for explaining this to me and for also pointing out that she has, atypically, extra satellite spots on the forewing.
Excerpt from the plaque:
New Caledonian Giant Gecko: These lizards are the largest living species of gecko, weighing over 400g (nearly a pound). Living in the trees, these lizards need to be able to climb. Luckily, they have super sticky feet. Their toes are covered in microscopic hairs (setae) which are even further split into spatula. These hairs use molecular forces to stick to leaves and other surfaces.

The young caterpillar is densely covered with yellow setae. The older caterpillar's setae are either pale yellow or white. All instars have thin, black setae on the first and third abdominal segments. On the eighth abdominal segment, there is one tuft of black setae. The caterpillar will reach a length of 50 mm (2.0 in).[3] While there are numerous reports of the larval hairs of this species sometimes causing skin irritation in humans, there is no evidence that they possess any form of venom.[4]
Leg 2 with knobbed tenent setae...(2 just visible) IMHO of course :)
Zerene stack : 7 (not the best because of a little movement by the springtail)
Another one with some color with hopefully enough detail...
Many attempts focused on the legs to be able to photograph the tenent setae on the footcomplex this time.
Found in the back of the forest (after pollismolen) over the swamp path at the end of it along the water.

One of my favourite caterpillars to come across, I think rather subtly beautiful. Completely covered in long, hairlike setae arranged in spreading tufts.
35mm in length.

I didn't find a paddle-like interocular setae or perhaps I don't know what I must see...
Scutellinia setosa is a species of apothecial fungus belonging to the family Pyronemataceae. Its fruit bodies are disc-shaped with thick black "hairs" (setae) around the cup rim. The smooth, ellipsoid, spores measure 11–13 by 20–22 µm and contain numerous oil droplets. The asci (spore-bearing cells) are roughly cylindrical, measuring 300–325 µm by 12–15 µm. Originally described from Europe, it is also found in North America and Central America, where it grows on the rotting wood of deciduous trees. (Wikipedia)
I was back at the same place in Kaulille and found this springtail again deep under the many leaves of a walnut tree. This one is on a stalk of a leaf from this tree.
No clavate tenent setae ...

Look black and purple pedipalps with a nice white setae and green-turquoise eyes ... so cute and I love it
My second favorite species with this a rare jumping spider in France : Attulus (Sittius) penicillatus.
---------------------------
Regardez les pédipalpes noir et violet avec de superbes soies blanches, et ses yeux turquoises, caractéristiques du mâle.
Je l'adore ! C'est pas seconde espèce favorite chez les Salticidae françaises. Attulus (Sitticus) penicillatus est relativement rare en France.
One of many similar green weevils. It has elongate scales and a covering of fine, pale setae. It has a tooth on the femora which are dark coloured under the scales. The elytral striae are clearly visible (lacking scales) and the apex of the scape is dark.

Monarch butterfly caterpillar starting to feed on a milkweed plant. The caterpillar is in the fifth stage of development before becoming a pupae.
The caterpillar goes through five major, distinct stages of growth and after each one, it molts. Each caterpillar, or instar, that molts is larger than the previous as it eats and store energy in the form of fat and nutrients to carry it through the nonfeeding pupal stage. 5th instar with the white spots visible on the prolegs.
The first instar caterpillar that emerges out of the egg is pale green and translucent. It lacks banding coloration or tentacles. The larvae or caterpillar eats its egg case and begins to feed on milkweed. It is during this stage of growth that the caterpillar begins to sequester cardenolides. The circular motion a caterpillar uses while eating milkweed prevents the flow of latex that could entrap it.
The second instar larva develops a characteristic pattern of white, yellow and black transverse bands. It is no longer translucent but is covered in short setae. Pairs of black tentacles (stinkhorns) begin to grow. One pair grows on the thorax and another pair on the abdomen.
The third instar larva has more distinct bands and the two pairs of tentacles become longer. Legs on the thorax differentiate into a smaller pair near the head and larger pairs further back. These third stage caterpillars began to eat along the leaf edges.
The fourth instar has a different banding pattern. It develops white spots on the prolegs near the back of the caterpillar.
The fifth instar larva has a more complex banding pattern and white dots on the prolegs, with front legs that are small and very close to the head.

Again I went to visit the birch trees in Hageven. This is another attempt to get a picture of the furca of these wriggling springtails.
I thought that he was a Vertagopus arboreus, but I doubt. He's not very purple, and we can see pale pattern on his head and body.
I don't think he's a Desoria because of pale legs and very short body's setae ? I have a picture where I can see setae just above the claws too.
Help !

The common green bottle fly (biological name Phaenicia sericata or Lucilia sericata) is a blow fly found in most areas of the world, and the most well-known of the numerous green bottle fly species. It is 10–14 mm long, slightly larger than a house fly, and has brilliant, metallic, blue-green or golden coloration with black markings. It has short, sparse black bristles (setae) and three cross-grooves on the thorax. The wings are clear with light brown veins, and the legs and antennae are black. The maggots (larvae) of the fly are used for maggot therapy.
Lucilia sericata is common all over the temperate and tropical regions of the planet, mainly the Southern Hemisphere: Africa and Australia. It prefers warm and moist climates and accordingly is especially common in coastal regions, but it also is present in arid areas.The female lays her eggs in meat, fish, animal corpses, infected wounds of humans or animals, and excrement. The larvae feed on decomposing tissue. The insect favours species of the genus Ovis, domestic sheep in particular. This can lead to blow fly strike, causing problems for sheep farmers, though L. sericata is not a major cause of blow fly strike in most regions.

The genus name Orgyia is from the ancient Greek word ὄργυια, órgyia - 'outstretched arms'. So named because, when at rest, the moth stretches forward its forelegs like arms.
The larvae are brightly colored, with tufts of hair-like setae, about 6 cm long. The head is bright red and the body has yellow and orange dots, with a black stripe along the middle of the back. Four white toothbrush-like tufts stand out from the back, and a gray-brown hair pencil is at the hind end. There’s a theory that the four white tufts mimic the external cocoons of parasitic wasps. Touching the hairs sets off an allergic reaction in many humans.
Quite funny moving fly (Czech name for it is "Propeller") found accidentally in 1600m altitude and brought home for one of my first real stackwork.

The common green bottle fly (Lucilia sericata) is a blowfly found in most areas of the world and is the most well-known of the numerous green bottle fly species. Its body is 10–14 mm (0.39–0.55 in) in length – slightly larger than a house fly – and has brilliant, metallic, blue-green or golden coloration with black markings. It has short, sparse, black bristles (setae) and three cross-grooves on the thorax. The wings are clear with light brown veins, and the legs and antennae are black. The larvae of the fly may be used for maggot therapy, are commonly used in forensic entomology, and can be the cause of myiasis in livestock and pets. The common green bottle fly emerges in the spring for mating.

This Salt marsh moth caterpillar (Estigmene acrea) seemed happy to eat the swamp milkweed leaf in peace. I wish I had seen a Salt marsh moth, they are quite worth the image search. I had not seen one before but they are evidently quite wide-spread across North America. You can see an aphid on the leaf's bottom and the residue of more on the stalk. There seemed to be as many aphid colonies as there were volunteer milkweed plants this spring. We didn't see as many butterflies but the garden's offering was in place.
