Entomology

Entomology, from the Greek words entomos (meaning segmented) and logia (meaning study of) is the scientific discipline focused on the study of insects. It is a sub-discipline of zoology (the study of animals).

 

Worldwide, the number of insect species is estimated conservatively by the International Union for Conservation of Nature to approach (or likely exceed) 950,000. Insects are critical components of Earth's ecological systems in their varied roles that range from pollinators to disease vectors to foodstuffs rich in protein.

Zebra Longwing Butterfly Last Updated on 2014-06-25 18:33:59 Zebra Longwing Butterfly (Heliconius charitonia) The zebra longwing butterfly or zebra heliconian, Heliconius charitonia, is unmistakable with its long narrow wings, which are striped black and pale yellow. This species is common in Mexico and Central America and it is also found in most of Florida and in some areas of Texas, where it can be seen year round. Occasionally it wanders farther north as far as South Carolina and some of the central states, although it is not likely to survive the cold. Florida designated this striking creature as its state butterfly in 1996. They fly slowly and gracefully and are not easily startled. They gather in roosts to spend the night returning to the same place daily; all this making it easy to observe them. After mating the female lays eggs on one of several species of passion flower plants Passiflora. The caterpillars feed on these plants... More »
Larva Last Updated on 2014-06-13 19:44:02 A  larva is a distinct juvenile life stage associated with certain faunal species, most notably with certain butterfly, moth and a gamut of other arthropod, chordate, annelid, mollusk and echinoderm species. A larva typically has a morphology that is very different from its adult stage, both in overt appearance and in organ functionality; in fact, the larval habitat itself can be totally disjunct from that of the adult. The  larval life stage is also frequently found to a wide number of faunal parasites. Charles Darwin was one of the first to note the role of larval adaptation in the process of speciation. [1] The normal plural form of the term is based upon its Latin origin: hence, larvae.   Larvae are distinctly occuring life stages chiefly found in certain species within the phylla Arthropoda, Chordata, Mollusca, Echinodermata, Annelida and Cnidaria....

Biophony is the melodic sound created by such organisms as frogs and birds; geophony, the composition of non-biological sounds like wind, rain and thunder; and anthrophony, the conglomeration of noise spawned by human activity.

Insect repellents can be used at all ages unless the label specifically states an age limitation or precaution. As long as you read and follow label directions and take proper precautions, insect repellents with active ingredients registered by the U.S. Environmental Protection Agency (EPA) do not present health or safety concerns. The U.S. Food and Drug Administration (FDA) recommends using products that contain active ingredients registered by EPA for use on skin and clothing. EPA registration of insect repellent active ingredients... More »
