Butterfly fossils have been well covered by Grimaldi & Engel (2005), who point out their weakness in resolving the sister group of the Rhopalocera: butterflies of 45 Mya are much like their living counterparts. The first fossil was formed around 40-50 million years ago.
The Lepidoptera fossil record encompasses all butterflies and moths that lived before recorded history. The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization , such as lakes and ponds, and their juvenile ...
Many species have long larval life stages while others can remain dormant in their pupal or egg stages and thereby survive winters. [36] The Melissa Arctic (Oeneis melissa) overwinters twice as a caterpillar. [37] Butterflies may have one or more broods per year.
At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
A study found a group of painted lady butterflies traveled 2,600 miles across the Atlantic Ocean without stopping. Experts say it may be a world record for insects.
Evolution has produced astonishing variety of appendages in insects, such as these antennae.. The most recent understanding of the evolution of insects is based on studies of the following branches of science: molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology, bioinformatics and scientific computing.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
