How to Identify Southern Black Widow?
More Effects of Southern Black Widow
The brown Widow (Latrodectus geometricus) is a lighter color with an orange hourglass shape on its abdomen, different from the black widow. They are known as "cobweb spiders" because they have an odd way of making webbing. Brown Widows have a toxic bite which is weaker in the males. It is said that brown Widows regularly fight for territory against black widows.
The redback spider (Latrodectus hasselti) hunts large creatures, including trapdoor spiders (Ctenizidae), king crickets (Anostostomatidae), and even small lizards. It will commonly steal prey off of other spiders' webs too. These spiders bite humans frequently, but only the females pose a serious threat. Female bites could lead to illnesses and even death in extreme cases.
Within its silk-woven retreat, latrodectus mirabilis is recognized for its potent venom, which is a complex neurotoxin affecting the nervous system of smaller prey items, and occasionally deters larger predators. During its life cycle, this species exhibits sexual dimorphism; with mature females adorning a dimensional abdomen showcasing a striking hourglass marking, while males are markedly more diminutive and subdued in appearance. Latrodectus mirabilis adapts by strategically crafting irregular, scaffolded webs to ensnare unsuspecting insects.
Distinguished by its striking red and black markings, katipo possesses a unique neurotoxic venom, which it uses to immobilize its prey, primarily small invertebrates. During its juvenile phase, its coloration differs vastly, displaying white, yellow, and orange marks that gradually darken as it matures. Preferring to dwell in sand dunes near the coast, this species has a specialized habitat preference, which is reflected in its careful selection of nesting sites that provide both shelter and ample hunting opportunities.
Latrodectus tredecimguttatus is black in color, similar to most other widow species, and is identified by the thirteen spots which are found on its dorsal abdomen (the species name is Latin for "with thirteen spots"). These spots are usually red in colour, but may also be yellow or orange.The female of the species has a body length of about 7 - 15 mm, while the male is smaller and reaches 4 - 7 mm at best.
The western black widow (Latrodectus hesperus) is one of the few spider species that can harm humans. Pain from a bite can last up to twelve hours, but they do not bite unless provoked. The western black widow is also known for "sexual cannibalism." The female tend to eat the males after mating.
The northern black widow spider (Latrodectus variolus) matches other black widow spiders (Latrodectus) in appearance. The difference in this one is that the hourglass appears broken on the northern black widow spider. A bite is dangerous and can cause pain, rigid muscles, and vomiting. It is heavily suggested to seek out a doctor if bitten.
Adorned with a blend of hues forming cryptic patterns, phylloneta pictipes possesses the remarkable ability to fabricate intricate webs utilizing its silk, which exhibits exceptional strength and elasticity. Mainly nocturnal, this species employs a unique hunting strategy by relying on the vibrational cues transmitted through its web to detect and swiftly immobilize prey with a paralyzing bite before consumption.
Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.
The monarch butterfly (Danaus plexippus) is the most recognizable butterfly in North America. It is best known for its appearance, but should be better known for the fact that it has a 3000-mile migration that takes the butterfly 4 generations to complete. Their diet is also a natural deterrent for predators, as they eat milkweed, a poison that induces vomiting.
The japanese rhinoceros beetle (Trypoxylus dichotomus) is a massive beetle about the size of the palm of a hand. It's distinguished by its long Y-shaped horn, which it uses to fight other males with. It's a nocturnal bug that feeds on sap and sweet fruits. This species is sometimes kept as a pet due to its unique appearance and simple care requirements.
The silken threads produced by silkworm during its larval stage have been highly coveted for millennia, manifesting as a luxurious fabric in human society. Remarkably, this creature has a singular diet, feeding exclusively on the leaves of its primary host plant from which it extracts the necessary nutrients to facilitate its transition into a non-feeding, winged adult.
Menelaus blue morpho (Morpho menelaus) is a gorgeous butterfly with large, royal blue wings. Linnaeus named the genus Morpho the Aphrodite-Ancient Greek goddess of love and beauty for its extreme beauty. It is native to tropical rainforests. Though many butterfly gardens now cultivate them in captivity, there are still many people who never get a chance to see them.
While the atlas moth (Attacus atlas) can't tell you where to find your country on the map, it does earn its name through other means. It is one of the largest moths in the world, with a wingspan that is far larger than its body, creating an abnormal comparison. In India, their silk is gathered in a non-commercial capacity and is considered to be more durable than the domestic silkworm.
Both sexes reach about 5 mm in body length. Females and immatures of both sexes are brown but have color patterns by which they can be distinguished from related species. Also, the males dance to attract females.
Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.
