Of the 220,000 species of Lepidoptera, about 45,000 species are butterflies, which probably evolved from moths. Butterflies are found throughout the world, except in Antarctica, and are especially numerous in the tropics; they fall into eight different families.
First non-marine eukaryotes move onto land. They were photosynthetic and multicellular, indicating that plants evolved much earlier than originally thought. [53] 750 Ma Beginning of animal evolution. [54] [55] 720–630 Ma
In the so-called "macrolepidoptera", which constitutes about 60% of lepidopteran species, there was a general increase in size, better flying ability (via changes in wing shape and linkage of the forewings and hindwings), reduction in the adult mandibles, and a change in the arrangement of the crochets (hooks) on the larval prolegs, perhaps to ...
The Death Valley expedition was an 1891 expedition to discover the geographic distributions of plants (phytogeography) and animals in California's Death Valley. [1] It was the first of a series of expeditions funded by an 1890 act of the United States Congress. [1] The expedition included biologists, naturalists, botanists, and zoologists.
July 2024 was the hottest month ever recorded in Death Valley, with a mean daily average temperature over the month of 108.5 °F (42.5 °C). [34] Four major mountain ranges lie between Death Valley and the ocean, each one adding to an increasingly drier rain shadow effect, and in 1929, 1953, and 1989, no rain was recorded for the whole year.

In 2022, over 1 million people visited the national park. Here’s what we know about the valley dubbed as one of the hottest places on Earth
Zabriskie Point is a part of the Amargosa Range located east of Death Valley in Death Valley National Park in California, United States, noted for its erosional landscape. It is composed of sediments from Furnace Creek Lake, which dried up 5 million years ago—long before Death Valley came into existence.
The first insects were landbound, but about 400 million years ago in the Devonian period one lineage of insects evolved flight, the first animals to do so. [1] The oldest insect fossil has been proposed to be Rhyniognatha hirsti , estimated to be 400 million years old, but the insect identity of the fossil has been contested. [ 3 ]
