A thirsty juvenile yellow paper-wasp (Polistes olivaceus) drinks water from a small puddle on a wall during a heat wave in West Bengal. The state is experiencing an intense heat wave, with temperatures in some areas exceeding 45.1 degrees Celsius. Yellow paper-wasps are often found near water sources as they need to stay hydrated, particularly during hot and dry conditions. Wasps do not merely drink water; they also mix it with wood pulp to construct their nests, use it to cool their nests on hot days, and share it with their nest mates and larvae. These insects collect and transfer water by first swallowing it and then regurgitating it into the mouths of other wasps, in a process known as trophallaxis. Wasps can often be found hovering near water, which is vital for their hydration, especially in extreme heat and dryness. However, they must be cautious because if their wings become too wet, they will be unable to fly. This photo was taken in Tehatta, West Bengal, India on April 22, 2024.

The Brown Marmorated Stink Bug (Halyomorpha halys) is an insect in the family Pentatomidae, native to China, Japan, Korea, and other Asian regions. The Brown Marmorated Stink Bug (BMSB) was accidentally introduced to the United States in 1998. It is currently spreading throughout most of eastern and western North America, with the highest concentrations found in the Mid-Atlantic region. The BMSB is proving to be a nuisance for homeowners and can be devastating for farmers. It is feeding on a variety of plants, including fruit trees, ornamentals, and some crops. It is also entering houses in large numbers on warm fall days in search of overwintering sites. Adults are about 17 mm long and are shades of brown on both the upper and lower body surfaces. They are shield-shaped and almost as wide as they are long. The BMSB has piercing-sucking mouthparts and is feeding on fruits, seeds, stems, and leaves. It can switch hosts throughout the season, moving from plants with early-ripening fruits to those with late-ripening fruits. Most stink bugs do not bite, sting, or spread disease. The most harm most stink bugs cause is the ill-smelling substance they release as a defense tactic or if accidentally crushed. A Brown Marmorated Stink Bug is being observed sitting on potatoes and leaves of clover in Tehatta, West Bengal, India, on April 2, 2024.

A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonflies are known. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies are predatory insects, both in their aquatic nymphal stage (also known as ''naiads'') and as adults. In some species, the nymphal stage lasts up to five years, and the adult stage may be as long as 10 weeks, but most species have an adult lifespan in the order of five weeks or less, and some survive for only a few days. They are fast, agile fliers capable of highly accurate aerial ambush, sometimes migrating across oceans, and often live near water. Fossils of very large dragonfly-like insects, sometimes called griffinflies, are found from 325 million years ago (Mya) in Upper Carboniferous rocks.

Most of Pyrrhocoridae is a family of insects that are red-colored and are known as red bugs or called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. Like other true bugs, cotton stainers suck fluids from their host plants. The only part of the cotton plant affected by this pest is the flower and the seed capsule or boll. As this develops, the insect thrusts its rostrum between the carpels and sucks fluids from the still-soft seeds inside. Micro-organisms are admitted in the process and may make the boll contents rot or the lint become discolored. Meanwhile, the seeds wither, the fibers may fail to expand and the boll may abort. When the seeds of a host plant ripen and it becomes unsuitable, the adult insects migrate to new host plants of the same or different species. While away from their hosts, they feed on the nectar and fruit of non-host plants and can survive for several days without food. A nymph of Pyrrhocoridae feeds fruit with a saliva-like substance, known as proboscis (rostrum), a long tube-like mouth part by which hemipterans feed, with the help of it the fruit is hanging on Its mouth at Tehatta, West Bengal; India on 15/08/2023.
