Drakensberg Creeper (Opisthacanthus validus) #CritterThursday

Image
Learn more at https://abt-edu.com Scorpions stridulate by rubbing their chelicerae (mouthparts) together to produce a hissing sound. In some cases, they may drag the telson (sting) over the body segments (tergites) to produce a sudden scraping sound in an attempt to frighten off a predator. This is a medium sized scorpion of around 9 cm with the tail extended.   It is black in colour, but often with a muddy appearance. It sometimes has lighter coloured legs and a lighter tipped tail. It is common across its range, occurring under rocks often at high altitudes in areas like the Drakensberg.The sting of this species may cause pain but is not medically important.

Jumping spiders are a group of spiders that constitute the family Salticidae.#CritterThursday

Learn more at https://abt-edu.com As of 2019, this family contained over 600 described genera and over 6000 described species,making it the largest family of spiders at 13% of all species. –Wikipedia Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large. Although jumping spiders are generally carnivorous, many species have been known to include nectar in their diets. Jumping spiders conduct complex, visual courtship displays using both movements and physical bodily ...

Spiders are arachnids, not insects. Other members of the arachnid family include scorpions, mites, ticks and harvestmen.#CritterThursday

Learn more at https://abt-edu.com The greatest threat to spiders is habitat loss, although some spider species are also threatened by the pet trade. Most species are carnivorous, either trapping flies and other insects in their webs, or hunting them down. They can’t swallow their food as is, though—spiders inject their prey with digestive fluids, then suck out the liquefied remains. Though not all spiders build webs, every species produces silk. They use the strong, flexible protein fiber for many different purposes: to climb (think Spider Man), to tether themselves for safety in case of a fall, to create egg sacs, to wrap up prey, to make nests, and more. Most spider species have eight eyes, though some have six. Despite all of those eyes, though, many don’t see very well. A notable exception is the jumping spider, which can see more colors than humans can. Using filters that sit in front of cells in their eyes, the day-hunting jumping spider can see in the red spectrum, green s...

Investigating Sugar Ant's (Camponotus) #CritterThursday

Learn more at https://abt-edu.com This species vary greatly in shape, size and colour. They range from 2.5 to 15 mm, and are some of the most often seen ants due to their size and often bright in colouring. They often nest in a variety of sites ranging from holes in wood to the roots of plants, twigs of trees and shrubs, between rocks or in the soil. They can also be seen during the day however, they are most active at night. They are unable to sting, but they do possess strong mandibles which can bite. In self-defense these ants are also able to spray acid from their abdomens to deter predators. They feed on dead and lives insects, household waste and are attracted by sweet food. They rarely enter houses and the ant’s life cycle passes through egg, larva, pupa and adult phases. Castes: Ant colonies consist of various castes which perform different functions in the colony. Reproductives - The reproductive males and females have the task of reproducing. Depending on the ...

FACT : Butterflies Taste With Their Feet. #CritterThursday

Image
  Here are a few interesting facts : Butterflies and moths are part of the class of insects in the order Lepidoptera. Butterflies are flying insects with large scaly wings. Like all insects, they have six jointed legs and three body parts: the head, the thorax and the abdomen. The wings are attached to the thorax and they also have a pair of antennae, compound eyes and an exoskeleton. The butterfly starts its life as an egg, laid on a leaf. The caterpillar (larva) hatches from the egg and eats leaves or flowers. It loses its skin many times as it grows, increasing greatly in size. Eventually it turns into a pupa, or chrysalis and finally a beautiful adult butterfly emerges and the cycle continues. An adult butterfly has a very short life: just three to four weeks. However, the entire life cycle of a butterfly can range between 2 and 8 months, depending on the species. It might sound strange to us humans, but butterflies rely on their feet to taste food. Their feet have taste sensor...

Millipedes have a lot of legs, but not as many as most people think...#CritterThursday

Image
Let's start with the basics: Millipedes are not worms, nor are they  insects . Insects have six legs, and obviously millipedes have many more. It turns out scientists did not choose the Latin prefix in their name, "milli-," meaning 1,000, as a way to convey the precise number of legs these organisms have. Their colloquial nickname "thousand leggers" is not accurate either. Millipedes fall within a phylum of organisms called  arthropods , a category that includes invertebrates as diverse as spiders, scorpions and butterflies. All arthropods have in common a hard exoskeleton, segmented bodies and jointed legs. What distinguishes millipedes is that for each segment of their body, they have two pairs of legs, instead of one pair as you would see with, say, centipedes. This gave way to the more accurate name used by scientists:  diplopoda , meaning "double foot." Having so many legs is part of what makes millipedes so adaptive.  Fossil evidence suggests  th...

Join ABT in learning more about the Emperor Moth #ConservationTuesday

Image
©Lafras Taljaard The moths are easily identifiable by their markings, which feature a large orange eyespot on each hind wing and two black and white bands isolating two smaller eyespots. Males have long, feathery antennae that they use to find a mate during their brief three-to-four-day lifespan. Gonimbrasia belina  is a species of  emperor moth  which is native to the warmer parts of  southern Africa . Its large  edible   caterpillar , known as the  mopane worm , feeds primarily but not exclusively on  mopane tree  leaves. Mopane worms are an important source of  protein  for millions in the region. The species was first described by  John O. Westwood  in 1849. Like most caterpillars, the mopane worm's life cycle starts when it hatches in the summer, after which it proceeds to eat the foliage in its immediate vicinity. As the  larva  grows, it moults four times in its five larval stages, after which the mopane w...

Investigating Antlions with African Bush Training #CritterThursday

Learn more at https://africanbushtraining.com ©Hannalize Van Der Colff The Antlion,  also known as Lacewings, are neither ant nor lion. It is actually the larvae of about 2000 species of the family myrmeleontidae. It got its name due to the fact that they are predators and mainly feed on ants. Antlions are found in sandy areas such as dry woodland, sandy river banks and even on roads. Antlion larvae eat small arthropods, while adults of some species eat pollen, nectar or other small insects. The  antlion  larva has a robust fusiform body, a very plump abdomen, and a thorax bearing three pairs of walking legs. Antlion larvae are very popular for their hunting habits. These tiny predators will dig small pits and wait under the sand with just its jaws above the surface waiting for insects such as ants to pass by. When the unsuspecting prey falls into the pit and try to escape, the antlion will alternate the sides of the pit causing it to collapse and bring their prey even cl...
