flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

Bee populations are declining, and neonicotinoid pesticides continue to be investigated—and in some cases banned—because of their suspected role as a contributing factor. However, limitations in sampling and analytical techniques have prevented a full understanding of the connection. Now, researchers describe in the ACS journal Environmental Science & Technology a new approach to sample neonicotinoids and other pesticides in plants, which could explain how bees are exposed to […]

Australian ants prepared for 'Insect Armageddon'
on July 16, 2019 at 2:48 pm
Researchers studied ants in the Simpson Desert for 22 years and found that local changes in climate, such as long-term increases in rainfall, combined with human efforts to restore ecosystems, may have led to increased numbers of species—rather than the declines which might be expected in such unpredictable conditions. […]
