In order to speed up taxonomic identification, DNA barcoding is now been considered as an alternative tool for insect biodiversity identification in India and the World.
With the recent advancement in science, the new method called DNA barcoding, a tool of DNA-based taxonomy is used to identify known and unknown species on the basis of the pattern of nucleotide arrangement in a fragment of DNA from target species. Several biodiversity indices were used to study the species richness in the area. So, there is increasing need for taxonomic information and services in our society, particularly for biodiversity assessment for attaining an environmentally sustainable future. Insect biodiversity has a significant role in the maintenance of the ecosystem. Insects are becoming extinct because of habitat loss, over-exploitation, pollution, overpopulation and the threat of global climatic changes. The diversity of insects is greater in the northeastern states, the Western Ghats and the Andaman and Nicobar Islands, and these areas also have a high level of endemism. Current estimate shows that out of nearly 63,760 species of insect species in India, about 21,166 species are endemic. India is one among the twelve mega biodiversity countries of the world, constitute nearly 7% of the world insect fauna.

Learn more about synchronous fireflies and how to experience their symphony of light.Insects are the world's most diverse group of animals on Earth, in terms of both taxonomic diversity and ecological function accounting 75 % of the known species of animals.Approximately 30 million species are found worldwide, of which about 1.4 million have been briefly described.Less than 3% of all species of insects have aquatic stages in some freshwater biotopes. North Carolina is one of the few places in the world to see synchronous fireflies, like Photinus carolinus. Repeat this call-and-response process another time or two as needed, and the male firefly will come to you in short order!įor those of us in or around North Carolina, a short trip beyond the backyard can yield a spectacular one-of-a-kind experience.and flash your penlight (again just a quick half-second flash) Let him flash again, then wait 2 more sec.and then flash your penlight in his direction (just a quick half-second flash) Identify a specific male firefly (one that’s flying around and flashing nearby).All you need is a small pen flashlight, or penlight, and a little patience! Speaking of which, you can actually encourage fireflies to come to you with this neat trick. So be sure to enjoy your firefly experience, but tread carefully when taking in nature’s amazing fireworks display. That said, “bear in mind that they are little animals that lead dangerous lives, and we want to try and do everything we can to avoid harming them,” Sorenson says. Every kid should catch a firefly once in a while. I think it’s really important for people to experience fireflies.
Fireflies control their flashing by regulating the oxygen level in their light-producing organs. It is generated through a chemical reaction in special organs in their abdomens.Ĭhemicals, enzymes, oxygen and energy-transporting molecules within cells all coalesce to create light. Fireflies’ trademark flashing light is a well-known example of bioluminescence.
Illuminating Insectsīioluminescence, or the ability of a living organism to produce light, is both breathtaking and rare. View the original data as an interactive map for comparison. Katz’ data (collected 11 years after the Harvard study) suggests firefly is becoming more popular, while fewer folks outside Appalachia and the Heartland use lightning bug exclusively. Overall, roughly 40% of respondents use “firefly” and “lightning bug” interchangeably, while about 30% each use one term exclusively. Lightning Bug: Which Do You Say? NC State alum, Josh Katz, created this map using data from a quiz he developed, based on the Harvard Dialect Survey, for The New York Times.
Homegrown sat down with Clyde Sorenson - NC State’s resident firefly expert and a luminary in his own right - to help shed light on the subject in this edition of Homegrown. If you’re like us, their mysterious glow has mesmerized you since childhood. Fireflies are found across North Carolina, with 30 to 40 species (and counting) identified in the state
