What is Entomology?

Entomology (from Ancient Greek ἔντομον (entomon), meaning ‘insect’, and -λογία (-logia), meaning ‘study of’[1]) is the scientific study of insects, a branch of zoology. In the past the term “insect” was more vague, and historically the definition of entomology included the study of terrestrial animals in other arthropod groups or other phyla, such as arachnidsmyriapodsearthwormsland snails, and slugs. This wider meaning may still be encountered in informal use. https://en.wikipedia.org/wiki/Entomology

Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular geneticsbehaviorbiomechanicsbiochemistrysystematicsphysiologydevelopmental biologyecologymorphology, and paleontology.

At some 1.3 million described species, insects account for more than two-thirds of all known organisms,[2] date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth.

16 Coolest Creepiest Spiders

Cave Robber
Until the year 2012, no one had ever heard of or seen a cave robber spider. That is until a team of scientists discovered the bizarre tiny creatures in some old forests of Oregon and California. The scientists did a whole bunch of research and finally declared these spiders were unique and brand new. The team had unearthed an entirely new species of spider. Cave Robbers were the first new family of spiders to be added to North America since way back in 1890. These type of arachnids prefer caves and densely darkened redwood forests.

Spiny Orb Weaver
These dazzling arachnids can grow up to 30 millimetres in diameter and can be found all over the world. Their name hails from the prominent spines that can be found all over their abdomens, which are typically shaped similar to that of a crab. These brightly colored spiders have a hardened exoskeleton which comes in a variety of color patterns including white, orange, or yellow with red markings. Lucky for us, spiny orb weaver spider bites tend to be relatively harmless to humans.

Goliath Birdeater
This gigantic breed of arachnid is listed in the Guinness Book of World Records as the world’s biggest spider. They typically weigh around 6 ounces with leg spans of roughly 11 inches…that’s about the size of a puppy! Here’s an image of a little girl playing with what we certainly hope is a fake spider but if it’s real, the spider in question would have to be one of these disturbing Goliath Birdeaters. These giant spiders belong to the tarantula family and can be found in rainforest areas such as northern Brazil and southern Venezuela. These creepy crawlers have the ability to regenerate damaged or lost limbs, have fangs strong enough to pierce a mouse skull, and have a defense mechanism wherein they release tiny barbed hairs which are said to be extremely painful and leave the victim itching for days.

Happy Face Spider
Found in the rainforests of Hawaii, this crazy-looking spider is best identified through the strange patterns which decorate their yellow abdomens and form, you guessed it, a smiley face. However, there are a few of these incredibly bizarre-looking creatures who sport frowny faces or even ones that appear to be screaming. Sadly, this unique spider is listed on the endangered list.

Peacock Spider
This Australian species of spider is best known for their brightly colored circular flaps which appear on the abdomens of the males, which is highly reminiscent to a peacock’s colorful patterned fan used to attract mates of the other gender. These strange yet beautiful arachnids are gifted with extremely acute eyesight and when courting a female will vibrate their hind legs and abdomen to create a more dramatic and enticing effect.

Diving Bell Spider
Some call these fearsome fellas Water Spiders as they are the only completely aquatic spiders found on Earth, more specifically Europe, Asia, the United Kingdom, and Siberia. These strange arachnids survive inside ponds, slow moving streams, and shallow lakes. They have no gills to breath underwater so they build underwater retreats composed of silk filled with a giant air bubble. This pocket of air usually retains a bell-like shape with a silvery shine. Most of this peculiar spider’s time is spent inside that bell and occasionally jutting out to feed on whatever unfortunate small aquatic invertebrate happens to be swimming by.
Before we reveal number one, let us know in the comments below which one of these spiders you thought was the creepiest and don’t forget to subscribe! And now…

Black Widow
These fearsome spiders can be found worldwide. You can identify them by their all black coloring and bright red hourglass-shaped marking which lines their abdomens. Males are smaller and less venomous than their female counterparts, making their bite relatively harmless. On the other end of this spider spectrum, femme fatale black widows practice sexual cannibalism. This means a female will devour a male after mating with him. If she works up a ravenous appetite that is, hence why most male black widow spiders pick their mate based on how long ago she finished her last meal, which they can sense through chemicals in her web. These notorious spider queens have deadly fangs which contain neurotoxins. One bite from an angry female black widow could prove to be fatal to most humans, if left untreated.
