A Look into the Families of Mecoptera

Migita and Moriyama (2004) declare that in unknown environments, animal behaves inappropriately by expressing their innate or learned behavioral patterns. A. vulgare are often found constantly moving around the edge of the Petri dish because the environment is unfamiliar and appears as an obstacle (Migita and Moriyama 2004). One observation of pill bug’s movement is when they follow each other. Males can detect females through distance chemical communication (Beauché and Richard 2013). Due to aggregation pheromone, the A. vulgare are attracted to each other.

In insect species with indirect sperm transfer, sperm is packed in a spermatophore that is either externally attached to the female 's genital opening or introduced into her bursa copulatrix. Sperm transfer is not immediate in these species, and consequently mate guarding has been suggested to function as a mechanism of guarding sperm until it is released from the spermatophore into the female (i.e. spermatophore guarding). Spermatophore guarding is relatively common in insect species with external spermatophores (e.g. Orthoptera; Alcock 1994; Simmons 2001), but supposedly absent in species with internal spermatophores and rapid sperm release (Simmons 2001). This study focuses on two hypothesis associated with mate guarding a tactic of many species that adjust their reproductive behaviour according to the apparent risk of sperm competition. The phenomenon of mate guard to consider sperm competition levels and evolution of internal spermatophore guard is wide spread in insects and other animals. We analyse two hypothesis one the rival exclusion followed by the next spermatophore renewal hypothesis. Results showed that as rival was introduced to the arena of mating of the distinctive original male (guard) in many cases showed a strong aggressive behaviour regardless of whether successively avert the rival. In the second hypothesis certainly majority of the incidents showed an attempt of

The creosote bush grasshopper has a simple body. It has a rounded head capsule which contains the compound eyes, chewing mouth parts, and the short thread-like antennae, which are always shorter than the rest of body (Estella, 2009). The middle thoracic segments and part of the abdomen are covered by a type of hard shield called a pronotum which extends from the first thoracic segment. The forewings are leathery but they are not used for flight. Instead, they protect the delicate hind wings. They also have long jumping hind legs, which enable them to leap well over 20 times their body length (Anonymous, 2015).

Despite its name the brazilian free-tailed bat is actually widespread throughout South, Central, and North America. The largest and well-known populations are found in Mexico and Texas.The population is a total between 95 and 105 million individuals, with Bracken Cave in Texas holding between 20 and 40 million individuals alone.

This online article provides useful information concerning the major classifications of nymphs. It clearly explains the two general groups nymphs can be divided into and thus provides insight into more basic knowledge about nymphs. This article on Tribunes and Triumphs sums up smaller divisions of nymphs as well. Although this article went abnormally in depth concerning nymph classification, the overall idea expressed in the article provided useful information,

The most extensive metamorphic changes of insects internal organs occur with development of the thoracic musculature required for flight, the arrangement of nervous system and the development of gonads [2].

Dasyatidae rays are relatively small and have a variety of patterns on their bodies ranging from bright blue spots to small white specks. Dasyatidae rays have eyes on the top of their heads and are equipped with keener eyesight than rays of the Myliobatidae family. Dasyatidae rays have stingers and barbs as a defense mechanism, while Myliobatidae do not. Sting rays are distinct in their morphology as they have a thick, spiny tail protruding from them that is often the same size as their body. M.mobular are relatively uniform in color and pattern distribution, with a dark grey-blue top and a stark white underside to protect them from predators. They lack the coloration, patterns, and variety of sting rays. While size has always been a constant factor in devil rays, the barbed, stinging tail is one morphological trait that drastically separates devil rays from sting rays. Sting rays can shed their stingers and replace their dermal coating faster than manta rays, which places sting rays closer to bony

I chose the article called “Swarms of CICADA Drones Could Aid Hurricane Research”. I chose this article because it sounded intriguing. The article explained how drones could help during natural disasters and such. These drones can go through a town after say a hurricane and it can help tell us the damage done, if there are any people in danger and it could help the volunteers locate the people in danger. I think this is incredible. I think that this is a great idea and could help save lives. A drone like this can not do anything but help, it is not gonna put people in danger or invade people's privacy, it could only help them. It can also tell the damage of the natural disaster which can be helpful when you do not know what to expect and then

It’s amazing the discoveries that are made every day. Between remote forests, the depths of the ocean, and even under our own feet, there are still thousands of discoveries yet to be made. I chose the Blackeyed-Satyr, a beautiful butterfly discovered in Brazil, in 2015. It is no wonder it took so long for this discovery to be made is it resides in a very small geographical area. This amazing specimen resides only within a 311-mile portion of tropical forest in the Northern Amazon basin of Brazil, Colombia and Venezuela (Palermo, 2015).

The male Latrodectus hasselti can detect the chemical from females’ webs to determine the status of her virginity. From the study by Stoltz, McNeil and Andrade (2007), they found that males redback spiders will know which female is a virgin or not is based on the pheromone released in their web. The specific chemical they found was methanol, which the virgin females will secrete in their webs. A female Latrodectus hasselti advertise to the males that she is a virgin so males will go to her web for mating, and in return the males will get

There has been contention over the classification of the spring peeper (Pseudacris crucifer) over several decades. P. crucifer was reclassified in 1986 from the genus Hyla into both the newly created genus Parapseudacris (Hardy and Borroughs 1986) and into the preexisting genus Pseudacris (Hedges 1986). The later became scientifically accepted based on Hedge’s results in genetic testing, and was further supported later by his observation of behavioral and morphological characteristics shared by the Pseudacris genus. Historically, P. crucifer was been split into two subclasses, P. c. crucifer and P. c. batramiana, based off locality and slight morphological variation (Harper 1939), however more recent studies further examining genetics no

The Argentine Cactus Moth, Cactoblastis cactorum Berg (Lepidoptera: Pyralidae), an invasive insect in North America, poses the serious threat to native, endangered opuntioid species in the southeastern USA as well as with the potential to cause a major infestation of commercial and agricultural cactus crops in Mexico. The Cactus Moth was first reported in the Florida Keys in 1989 and later spread throughout the Atlantic and Gulf coasts of the United States. The Cactus moth outbreak in the southeastern US possibly will affect the entire desert ecosystem because wild opuntioid species of these regions provide nesting sites and food for a variety of wildlife and contribute to soil stability. Efforts to control the North American spread of the

Observations: Female silkworms moths emit chemical signals that can be detected by male's sensory organs (antenna) far away.

In order to support their theory they use the sexual behaviour of scorpion flies Thornhill and Thornhill (1987), in which the male may gain sex from the female either by presenting a gift of food through a notal organ) during courtship or without a nuptial offering, in which case force is necessary to restrain her. Human males do not have a similar rape organ, but Palmer et al (2000) argue that the rape adaptation is found in the male psyche, however it is not only the male psyche that leads to rape. As Darwinists, Thornhill and Palmer see themselves as having the only valid explanation of rape, they dismiss social science and feminist theories.
