A large rove beetle with extended exposed abdomen covered by hardened plates and composed of 8 segments. Uniformly black body covered in fine, black hairs (setae). Shortened wing cases (elytra) which cover the thorax, concealing a folded second pair of wings which enable flight.
Male Phidippus audax bold jumping spider. This species is one of the first to appear after the long winter months. Photographing a male can be quite challenging as they rarely sit still. A common species, yet I never tire of their friendly and familiar faces.
Single exposure, hand held, diffused flash.
Notes: During the winter they may form aggregations in protected spaces. Females lay their eggs under the bark of trees or shrubs. Male TBL 6-13 mm.
Hybos culiciformis can reach a size of 3.5 to 5.5 mm. It has large yellowish thoracic setae, row of setae on the mid femur and strong setae on mid tibiae. Mesonotum is finely dusted. It flies from June to September and feeds on small insects.

The male of this species is one of the most impressive looking jumping spiders in North America. The female may not be as visually striking as the male, yet she's still quite beautiful in her own way.
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.
The hymenopteran family Platygastridae (sometimes incorrectly spelled Platygasteridae) is a large group (over 4000 species) of exclusively parasitoid wasps, mostly very small (1–2 mm), black, and shining, with geniculate (elbowed) antennae that have an eight-segmented flagellum. The wings sometimes lack venation, though they may have slight fringes of setae.
The traditional subfamilies are the Platygastrinae and the Sceliotrachelinae. The former subfamily includes some 40 genera, all of which are koinobionts on cecidomyiid flies; the wasp oviposits in the host's egg or early instar larva, and the wasp larva completes development when the host reaches the prepupal or pupal stage. The latter subfamily is much smaller, including some 20 genera, and they typically have the rudiments of a vein in the forewings. They are generally idiobionts, attacking the eggs of either beetles or Hemiptera.
The former family Scelionidae is now considered to be another subfamily of Platygastridae, along with the subfamilies Teleasinae and Telenominae. The oldest known record of the group is an indeterminate specimen from the Burmese amber.

The Hickory Tussock Moth is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species is widely distributed in the eastern half of North America. In other species in this family, the caterpillars acquire chemical defenses from their host plants, so they are potentially toxic or unpalatable.
The larva, a caterpillar, is completely covered in long, hairlike setae arranged in spreading tufts. The hairs cause itchy rashes (contact dermatitis) in many people, particularly those prone to allergies, and may resemble exposure to urushiol. They are microscopically barbed and may rarely cause serious medical complications if they are transferred from the hands to the eyes, but in over 350 documented cases, most were asymptomatic within 24 hours, and none involved anaphylaxis.

I was fascinated to see this larval moth just hanging in the air with apparently no means of doing so. I guess there was a fine filament of silk holding it to the tree above. The backdrop is the river and the light was just right to show off this beautiful little caterpillar.

Monarch caterpillar in its fifth stage of development.
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. – Wikipedia

This species is distributed from Hungary to as far east as Mongolia and China. The most important distinguishing character is the brown mystax ("mustache") in males, which is white in the case of S. elegantulus, black and "bushy" on S. albofasciatus (the latter has entirely black legs). Stichopogon scaliger, males of which may have yellow-brown mystax, has a different abdominal pattern and lacks the relatively long, dark acrostichal setae on the mesonotum of S. barbistrellus.
Lonchoptera is a genus of spear-winged flies (Lonchopteridae). Their common name refers to their subacute (pointed) wings, which have a distinct and sexually dimorphic venation.
Species in Lonchoptera are tiny to small, at 2–5 mm (0.079–0.197 in), slender, and yellow to brownish-black bristly.
The larvae are dorsally flattened, with two pairs of head bristles, and feed on rotting vegetable matter., including in one case brussels sprouts.
This genus can be distinguished from other spear-winged flies by several traits:
foreleg tibiae have dorsal setae in the middle
foreleg tarsi thinner than foreleg tibiae
pointed wingtip without apical brown spot.

The banded garden spider is a large species, with a generally ovoid form and bright markings. Mature females may be 13-14.5 mm when fully extended and the carapace of the body typically between 5-6.5 mm in length. Males are substantially smaller, with a body length of only about 1/3 that of the female. Adult males also have prominently enlarged pedipalps projecting from the side of the head and these are used in sperm transfer.
The back of the spider is covered with silvery setae. Numerous dark lines cross the body and yellow banding is usually present as well. The legs are dark yellowish-brown with darker rings.
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.

Selenocosmia crassipes, synonym Phlogius crassipes, also known as the "Queensland whistling tarantula" (or "barking spider") is a species of tarantula native to the east coast of Queensland, Australia. The name "whistling tarantula" comes from its ability to produce a hissing noise when provoked, a trait it shares with other Australian theraphosids. This hissing is produced by the spider stridulating a patch of setae associated with its chelicerae. It has also been called the "eastern tarantula". The species name crassipes is Latin for "fat leg" referring to the relatively fat front legs.
Selenocosmia crassipes can attain legspans of up to 22 cm (8.7 in). Its body length, from eyes to the rear of its abdomen, measures between 6 and 9 cm (2.4 and 3.5 in), making it the largest Australian tarantula. (Wikipedia)

First, I thought I encountered Deutonura conjuncta, because we are quite far from the Pyrenees.
But I see two setae on the dorso-internal tubercles of the 1st thoracic segment.
I believe there are only 2 bristles on the dorso-lateral tubercles of the 1st to 3rd abdominal segment (but an indication of their position on my photo would help me because I am not sure of their location).
So it would rather be a somewhat nordic monticola?

Yesterday I posted a shot of a Barred Owl on a fence post that had a caterpillar on it. I sent the image to U of A Entomologist John Acorn for an explanation and identification. Several contacts have asked for an update. John went out and collected it today. Here is his reply:
"The caterpillar has been dead for some time, killed by parasites. There are multiple exit holes where parasites emerged from the host's body. Most of the hairs (setae) have worn off, so it is not easy to recognize, but I think it is probably Acronicta dactylica, the Fingered Dagger Moth."
I expected to find this species on the heather there ...
Very beautiful area by the way ! I'll go back there again, but be warned, stay on the hiking trail !

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.

Calliphora vomitoria, known as the blue bottle fly, orange-bearded blue bottle, or bottlebee is a species of blow fly, a species in the family Calliphoridae...Blue bottle flies are typically 10–14 mm (3⁄8–9⁄16 in) long, almost twice the size of a housefly. The head and thorax are dull gray, and the back of the head has long yellow-orange setae. The abdomen is bright metallic blue with black markings. Its body and legs are covered with black bristly hairs.
A gift from Frans Janssens. :-)
I could make a lot of photo's but it's not an easy one for determination...
Ocelli BDE are in straight line, not seen any legs with clavate tenent setae so until now it's Isotominae.
In the mean time Frans Janssens figured it out ! See comment...
On monday, I was back on the heather in Opglabbeek early in the morning. At the same place I found this time a Heterosminthurus claviger male. Also several Sminthurus sp. and E. multifasciata.
Frans, I did find the paddle-like interocular setae...

Ah, geckos—those little marvels of the reptile world! Their lives are fascinating blends of adaptation, resilience, and stealth. Let me walk you through the world of geckos:
Overview
Geckos belong to a diverse family of lizards, with over 1,500 species found across the globe. These small, agile reptiles live in a variety of habitats, from rainforests and deserts to urban environments. Most geckos are nocturnal, which means they are most active during the night.
Physical Features
1. Sticky Toes: Geckos are famous for their adhesive toe pads, which allow them to climb walls and even walk upside down on ceilings. This is thanks to microscopic hairs (setae) on their toes that use molecular forces to stick to surfaces.
2.Tail Talents: Their tails serve multiple purposes. They store fat for energy and, in some species, can be detached to distract predators—a process called autotomy.
3.Colorful Variety: Geckos come in a stunning array of colors and patterns, which often help them blend into their surroundings as camouflage. Some species, like the day gecko, boast vibrant greens and blues.
Behavior and Lifestyle
1.Diet: Geckos are primarily insectivores, feasting on bugs, spiders, and other small invertebrates. Some larger species may also eat fruit or even small vertebrates.
2.Communication: Geckos are unique among lizards because they "talk"! They make chirping or clicking sounds to communicate, often for mating or territorial purposes.
3.Night Vision: With exceptional low-light vision, geckos can navigate and hunt efficiently in the dark.
Habitat
Geckos thrive in diverse environments, depending on the species. Desert-dwellers like the banded gecko are adapted to arid conditions, while rainforest species like the tokay gecko enjoy humid climates. Some geckos, such as house geckos, coexist comfortably with humans and can often be seen scurrying up walls.
Fun Facts
1.Regeneration: If a gecko loses its tail, it can regenerate a new one, though it might not be as perfect as the original.
2.Feet in Space: Geckos have even been studied in space to learn more about their unique climbing abilities.
3.Old Souls: Some gecko species have remarkable lifespans for reptiles, living up to 20 years in captivity.
A face only a mother could love perhaps, or a case of beauty is in the eye of the beholder? Reminds me of a bear in some ways.
