Wikipedia: Atta Atta Fabricius, 1805 is a genus of New World ants of the subfamily Myrmicinae. Atta is one of the most spectacular of the attines, and colonies can comprise in excess of one million individuals. Atta has evolved to constantly change foodplant, preventing a colony from completely stripping of leaves and thereby killing trees, thus avoiding negative biological feedback on account of their sheer numbers. www.factbook.org /wikipedia/en/a/at/atta.html   (411 words)

SKETCHES OF THE NATURAL HISTORY OF CEYLON The rim is frequently of a different tint from the centre, and one species which I have seen is quite startling from the brilliancy of its colouring, which gives it the appearance of a ruby enclosed in a frame of pearl; but this wonderful effect disappears immediately on the death of the insect. One species, about the third of an inch in length, is abundant in the hills, and especially about the roots of trees, where they pile up the earth in circular heaps round the entrance to their nests, and in doing this I have observed a singular illustration of their instinct. The larvæ of this species are green with white bands, and have a hump on the fourth or fifth segment. www.lakdiva.org /books/tennent/c12.html   (8153 words)

[No title] Interestingly, despite all species producing similar chemical compounds from the venom gland, these were found to elicit alarm behaviour in only those species that build nest envelopes, suggesting a link between chemical release of alarm behaviour and the evolution of nest architecture in Ropalidia wasps. In both species, they were secreted by females from two glandular sources, from tergal glands located on tergite 6 to 10 in M. annandalei and tergite 5 to 10 in M barneyi, and from posterior sternal glands located on sternite 6 and 7 in both species. Species and sex specific vibrational signals produced during the courtship are well suited for propagation through plants and to transmit the relevant information about the species and sex of the sender as well as provide the directional cue for locating the mate. www.canis.uiuc.edu /~schatz/databases/communication.insects.txt   (18109 words)

Last check: 2007-10-26) However, species identification of eastern specimens in the "fulva-rudis-texana" complex is virtually impossible, and, unfortunately, in the mesic forests of the southeast, these ants are common and abundant. This ant is a common and highly adaptable species, nesting in soil, under stones or logs, in decaying wood, leaf litter, hollow stems of plants, or under bark at bases of trees. Species of Leptothorax are of similar size to minor workers of Pheidole but in profile their mesosoma is usually flat (sloping mesonotum in Pheidole). www.cs.unc.edu /~hedlund/ants/PrintingPages/PheidoliniDBout.html   (9839 words)

Insects in ant colonies The behavior of these myrmecophiles shows that the surface of the ant's body must be covered with an unctuous, highly nutritious, and, it may be, antiseptic secretion, probably derived from the salivary glands of the host-ant or other members of the colony. Thenceforward they are objects of special care by the Pheidole workers, who tend them as their own offspring, not only in the pupal, but in the imago stage. Indeed, as this species of ant is almost blind, it seemed doubtful if they really could distinguish larval host from larval guest, the latter possibly being taken for a mere enlargement of the former's neck. www.antcolonies.net /insectsinantcolonies.html   (4088 words)

Tennent's Ceylon 1860. v1_p2_c06 It is particularly abundant in gardens, and on fruit trees; it constructs its dwellings by glueing the leaves of such species as are suitable from their shape and pliancy into hollow balls, which it lines with a kind of transparent paper, like that manufactured by the wasp. All the families, from the Papilionidoe to the Tineidoe, abound, and numerous species and several genera appear, as yet, to be peculiar to the island. In some of the heterocerous families several species are common to Ceylon and to Australasia, and in various cases the faunas of Ceylon and of Australasia seem to be more similar than those of Ceylon and of Hindostan. lakdiva.org /tennent/v1_p2_c06.html   (5476 words)

Systematics of the Mesynodites sensu lato genus complex All species within the subfamily Hetaeriinae are guests of ant or termite colonies and have evolved in association with a wide variety of hosts. Species within Mesynodites are associated with an unusually wide range of hosts for a single genus, including numerous species of army ants and leafcutter ants. In this work, 77 genera were included (mainly one species per genus) and keyed, the male genitalia were used as diagnostic characters for the first time for the subfamily, and a phylogeny of the included genera was generated using parsimony analysis. www.agctr.lsu.edu /arthropodmuseum/mesynodites.htm   (3427 words)

International Zoo News Vol. 46/7 The gorilla is an endangered and flagship species, yet there are still many individuals who die in captivity leaving no descendants, so that their genetic value is lost, reducing the variability of the captive population. In this species, because of its social complexity and the fact that many individuals are hand-reared, it is not easy to transfer animals from one group to another and have successful natural breeding. On 31 December 1998, the stock consisted of 1,393 mammals of 254 species and domestic breeds, 2,492 birds of 523 species, 438 reptiles of 86 species, 401 amphibians of 29 species, 4,172 fish of 353 species, and 5,639 invertebrates of 176 species, a total of 14,535 animals of 1,421 species. www.zoonews.ws /IZN/296/IZN-296.html   (20886 words)

The effects of food presentation and microhabitat upon resource monopoly in a ground-foraging ant (Hymenoptera: ...   (Site not responding. Last check: 2007-10-26) In at least two ant species, food presentation affected monopoly at baits; among all resource-defending ants, the microhabitats where ants foraged for food and the type of food located determined in part the frequency of monopoly and the number of foragers at the food item. Thus, we determined the presence of a leafcutter ant (Atta cephalotes) trail and carton-nesting termites (Nastutitermes spp.) within 5 m of the bait, and plants of the family Melostomaceae, and palms within 1 m of the bait. In most instances when split and clumped baits were shared by two or more ant species, the areas of the baiting platform utilized by each species where adjacent to one another, which suggests that these species had interacted with one another at the bait. rbt.ots.ac.cr /revistas/48-2-3/glynn.htm   (4926 words)

Davidson and her field assistants (Silvia Roces Castro and Beatriz Fuentealba Durand) during the period of September - November of 1983 - 1986, 1988, and 1998-2000. The majority of these species are or will be vouchered in the entomology collections of Peru’s Museo de Historia Natural (Javier Prado) Natural History Museum of Los Angeles County, although most of the Pheidole are in Harvard’s Museum of Comparative Zoology.
