Caterpillar Gets The Most From Food When Predator Is On The Hunt
2012-07-13 13:37:15

redOrbit Staff & Wire Reports - Your Universe Online While other animals beef up metabolism and stop growing or developing during a defensive period, hornworm caterpillars slow or stop eating but actually keep up their weight and develop a little faster in the short term. Hornworm caterpillars ate 30 percent to 40 percent less when threatened by stink bugs but weighed the same as their non-threatened counterparts as indicated by Ian Kaplan, a Purdue University assistant professor of...

John Neumann for redOrbit.com - Your Universe Online A team of biologists from Tufts University in Boston may have answered the question of what attracts fireflies to each other. Dr. Adam South, with supervision from colleague Sara Lewis, who have been studying fireflies for 20 years, used LED lights to mimic the flashes of amorous male fireflies. In the wild, females are very picky about what males they reveal themselves to during this part of the courtship routine. Females will only...

Nocturnal animals can steal bird feeders, ruin gardens, attack livestock and worse. Duncraft now offers the The Nite Guard Solar, a solar powered device that deters nighttime predators with a simple principle–a flashing red light that mimics the eye of another animal. It works! Predators feel threatened and stay away! Concord, NH (PRWEB) July 03, 2012 Nocturnal animals can steal bird feeders, ruin gardens, attack livestock and worse. Duncraft now offers the The Nite Guard Solar, a...

Researchers Find That Some Butterflies Share DNA

Brett Smith for RedOrbit.com Geneticists have made a startling breakthrough while sequencing the genome of a South American butterfly, according to a study published in the May 16 edition of Nature. More than 70 scientists from 9 different institutions were involved in the Heliconius Genome Consortium, which sequenced the entire genome of the Postman butterfly (Heliconius melpomene). They found that the insect and two other related species, Heliconius timareta and Heliconius elevatus,...

Plants Mimic Scent Of Pollinating Beetles
2012-04-04 03:33:16

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing scents of scarab beetles and thus adapted to the beetles unilaterally. The mutual adaptation between plants and pollinators therefore does not always take place....

Researchers Look Into Hoverfly Disguises
2012-03-23 08:46:47

Mimicry in the animal kingdom is a useful tool that many insects employ to make themselves appear more fierce in order to escape from becoming a meal. However, researchers have been puzzled as to how some of the worst mimickers still seem to escape certain demise. Researchers at Carleton University in Ottawa, Canada set out to find the nature of mimicry in one of these imperfect impersonators: the hoverfly. Some hoverflies have evolved to be nearly indistinguishable from bees and wasps,...

Image 1 - Male Snakes With Boosted Estrogen Attract Other Males
2012-02-11 04:28:47

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood — attracting dozens of other males eager to mate. This experiment in the famed garter snake caverns of Manitoba, Canada, was one of the first in a field setting to ever quantify the effects of estrogen as a stimulant of pheromones, scientists said, in...

Image 1 - Mimic Octopus Finds Mimicking Partner

[ Watch the Video ] The remarkable mimic octopus (Thaumoctopus mimicus), inhabiting the coast of Sulawesi in Indonesia, swims with relatively little fear of predators in the ocean with its remarkable ability to shift its shape, movements and colors to impersonate toxic lionfish, flatfish and even sea snakes. Recently discovered hanging out with this great mimic is the black-marble jawfish (Stalix histrio). Researcher and ichthyologist Luiz Rocha, from the California Academy of Sciences...

Caterpillars Mimic One Another For Survival
2011-12-17 04:53:44

A new study in the current issue of The Annals of the Entomological Society of America helps scientists better understand how organisms depend upon one another In the world of insects, high risk of attack has led to the development of camouflage as a means for survival, especially in the larval stage. One caterpillar may look like a stick, while another disguises itself as bird droppings. Though crypsis may have its advantages, University of Florida researchers uncovered some of the most...

Predators Drive Evolution Of Poison Dart Frogs' Skin Patterns
2011-11-22 04:10:01

Natural selection has played a role in the development of the many skins patterns of the tiny Ranitomeya imitator poison dart frog, according to a study that will be published in an upcoming edition of American Naturalist by University of Montreal biologist Mathieu Chouteau. The researcher's methodology was rather unusual: on three occasions over three days, at two different sites, Chouteau investigated the number of attacks that had been made on fake frogs, by counting how many times that...

Combtooth blennies are blennioids; perciform marine fish of the family Blenniidae. They are the largest family of blennies, with approximately 371 species in 53 genera represented. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments. Physical description The body plan of the Combtooth blennies is archetypal to all other blennioids; their blunt heads and eyes...

Flower-flies (also known as hover-flies) are a family of flies (Diptera), with the scientific name of "Syrphidae". As their names suggests, they are most often seen around flowers. The adults feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In certain species, the larvae are saprophytes, eating decaying plant and animal matter in the soil or in ponds and streams. In others, the larvae are insectivores and prey on aphids, thrips, and other...

The Monarch butterfly (Danaus plexippus) is a well-known North American butterfly with easily identifiable orange and black wings. The females have darker veins on their wings, and the males have a spot in the center of each hindwing from which pheromones are released. Monarchs are especially noted for their lengthy annual migration. They make massive southward migrations from August through October. A northward migration takes place in the spring. During these migrations the females...
