The class Insecta of the kingdom Animalia is a distinct class that levels down to a select few species that have the certain characteristics required to be classified into the class of Insecta. By basic entomology standards, classifying a species in the class of Insecta requires that the species have three body segments and have three pairs of legs. Species included in the class Insecta are beetles, butterflies, ants, and mosquitos. Insects are everywhere and are vital to an ecosystem, even those considered to be pests have a certain role that can only be carried out by that one species. “An insect is a six-legged animal that goes through…metamorphosis.”(Facklam 11) Each insect has three body segments the segments are divided into the head, home to the antenna, mouthparts, ocellus, and the compound eye; the thorax, which mainly includes the leg pairs as well as the fore and hind wings if any; and lastly the abdomen, which is home to the reproductive organs, the cercus, and the spiracle.(Spencer 6) Essentially insects are easy to identify as an insect due to their distinct features. Among these features, however, there
For example, the honey bee of the kingdom Animalia, phylum Arthropoda, class Insecta, order Hymenoptera, and family level Apidae, is considered a beneficial insect due to their role as pollinators and honey producers. Honey bees are an interesting species due to their partnership tendencies. Honey bees are commonly known as “social insects and live together in nests or hives. The honeybee is remarkable for the dancing movements it performs in the hive to communicate information to its fellow bees about the location, distance, size, and quality of a particular food source in the surrounding area.” (The Editors of Encyclopedia Britannica) Honey bees are highly beneficial to the environment and probably one of the most important insects in the animal

After conducting the experiments, the hypothesis was found to be incorrect. The data’s common trend was; as the beetle’s mass increased, the amount of weight it could pull decreased. One of the beetles tested had a mass of 1.6 grams and was able to pull only a mass of 18.6 grams. The second beetle had a mass of 1.8 grams and was able to pull 37.3 grams.
Outline the physical similarities between the (Blaptica dubia) cockroach and the cricket. Explain previous studies on physical stress in the cricket and in different species of cockroaches. Briefly discuss how the metabolic rate between the two species has been found to be very similar.
Forensic entomology is most commonly used in suspicious criminal cases. P.C. White (2010) suggests that insects are responsive to certain stimuli and from this we are able to capture an insight into an insects contribution to crime solving. We can determine many different aspects of a case by the presence of different insects colonising a dead body, blowflies for example, are the first to approach the body when its fresh. This is due to their preference of food sources. Ultimately, I will explicitly focus on the relevance of a blowfly at a crime scene.

Forensic entomology is the learning of all types of insects and how they connect with criminal investigation. Forensic entomology can tell us how long since the offspring’s death which is known as postmortem interval (PMI) and whether the body has been relocated since putting one foot in the grave, and what injuries it may have suffered. At the start of decomposition, insects launch a new community by hatching eggs on the remains; the eggs will emerge into cankers (larvae) that will graze upon the human organs and tissues. A Forensic entomologists can figure out what specific bugs are presently in the body and gauge how long the body has been left unprotected by investigating how far along the cankers have come; although, what is found isn’t
Forensic entomology is the study of insects and arthropods and their relation to a criminal investigation. Forensic entomology can determine the postmortem interval (PMI) or how long since the descendants’ death, whether the body has been moved since expiring, and what injuries may have been sustained (Ryan, 2011). When decomposition begins, insects establish a colony to lay eggs on the remains; these eggs will hatch into larvae that will eat the human organs and tissues. Forensic entomologists can determine the specific insects present in the body and estimate how long a body has been left exposed by examining the stage of development of the fly larvae; however, these findings are not always plausible. The fly larvae look and act different at each stage of development. The time required for stage development is not only affected by environmental influences such as geographical location, climate, and weather conditions, but also by type of insect. The forensic entomologist must consider these conditions when estimating the postmortem interval. Knowledge of insects, their life cycles, and their habits make entomological evidence a priceless tool for an investigation. Forensic entomology has proved its significance in a number of cases; though circumstances such as weather, temperature, and time of year clearly affect the development of insect infestation, and the expert must keep these in the forefront of his/her mind (Innes, 2000).
Most of the species from habitat one are Diptera. There was a total of thirteen Diptera’s in habitat one. Cup one had the least amount of individual species with four. Habitat two had more individual species than habitat one. There was a total of seventy-nine species from habitat two. Like in habitat one most of of the arthropods from habitat two were Diptera. The was a total of eighteen Diptera’s in habitat two. Cup six had most of the Diptera’s with thirteen. Orthoptera was second in the number of individuals with sixteen. Orthoporea’s are crickets and
Arthropods are animals belonging to the phylum Arthropoda, which is the largest of all phyla in the Animal Kingdom, with more than one million species, making them almost 80% of the whole kingdom. These include insects, arachnids, crustaceans and many more, most of which are quite small, the biggest being the Japanese Spider Crab with a leg span of 3.5 meters and the smallest being the microscopic Plankton.
Reproduction is one of the most powerful sources known on this earth. Reproduction allows animal, plants, and other organisms to thrive for generations. All organisms have to reproduce, otherwise their species will simply die out. Out of all of the organisms that reproduce, some of the most interesting include social insects of the Hymenoptera order. Social insects exhibit various interesting traits and strategies that they use for reproduction, such as the formation of a queen, worker reproduction, queen signaling or control, and sexual selection. Many of these traits and strategies can be seen in social wasp populations.
There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).
Insects are the most diverse group of organisms on the planet. They occupy most of the habitat in the world. Insects have served as a model group of organisms for tackling many biological queries. Butterflies (Class: Insecta; Order: Lepidoptera) have been used as a model for studies on ecology, development and population dynamics. Most of the species are highly seasonal and some have very restricted habitats. Butterflies are good indicators of climate and help us understand fluctuations in seasonal changes. They require specific ecological conditions for their growth and development. Monitoring butterflies helps us understand the overall diversity of a habitat as they are directly dependent on other factors such as availability of host plants and nectar plants. They also play a very significant role in
Insect, small, air-breathing animal characterized by a segmented body with three main parts—head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae, and in most instances, two pairs of wings. Insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science. That is why for every pound of human on the earth there are 10 pounds of insects. So that is why there are many reasons why insects are so successful, their exoskeleton, their size, their body function, the way they reproduce, and their development of metamorphosis.
The life cycle of a butterfly is perhaps one of the most beautiful and astounding processes in nature. The four stages a butterfly goes through to become the beautiful flying insects are just as interesting as the vibrant colors and patterns on the wings of the various species of butterflies. The four stages are as follows: the egg, the caterpillar, the pupa, and the emergence of the butterfly. Each stage is vital to the development of the adult butterfly. Perhaps the most interesting piece of the complicated puzzle that is the butterfly life cycle is the process of metamorphosis that happens in stage three. Similar to how a tadpole becomes a frog, a larva (caterpillar) morphs into a beautiful brilliantly colored butterfly.
Bees are small flying insects, buzzing around with its painful stings which always make people afraid and annoyed. What generally relate with bees are their roles in pollination and producing honey and beeswax. So it seems that bees might be nothing to human as it’s easy to find substitutes for honey as flavoring. However, this perception is mistaken. Without bees, aftermath.
