Junonia lemonias, the lemon pansy, is a common nymphalid butterfly found in South Asia. It is found in gardens, fallow land, and open wooded areas. This is another add on to the Cubbon Park apart the foliage.
It is brown with numerous eye-spots as well as black and lemon-yellow spots and lines on the upper side of the wings. The underside is a dull brown, with a number of wavy lines and spots in varying shades of brown and black. There is also an eye spot on the lower side of the fore wing. The wet and dry season forms differ considerably in colouration and even shape. In the wet season form the markings are distinct and vivid and the wing shape is a little more rounded. In the dry season form the markings are obscure and pale especially on the underside and the wing margin is more angular and jagged. This helps it camouflage in the dried leaf-litter. The lemon pansy is a very active butterfly and can be seen basking with its wings open facing the sun. It sits very low to the ground and can be approached easily. It feeds with its wings half open. It is a fairly strong flier and flies close to the ground with rapid wing beats and often returns to settle back in the same spots.
A wasp is any insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor an ant. This means that wasps areparaphyletic with respect to bees and ants, and that all three groups are descended from a common ancestor; the Apocrita form a clade.
The most commonly known wasps, such as yellow jackets and hornets, are in the family Vespidae and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently. Many of the solitary wasps are parasitoidal, meaning that they raise their young by laying eggs on or in the larvae of other insects. The wasp larvae eat the host larvae, eventually killing them. Solitary wasps parasitize almost every pest insect, making wasps valuable in horticulture for biological pest control of species such as whitefly in tomatoesand other crops.
Wasps first appeared in the fossil record in the Jurassic, and diversified into many surviving superfamilies by the Cretaceous. They are a successful and diverse group of insects with tens of thousands of described species; wasps have spread to all parts of the world except for the polar regions. The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length; among the largest solitary wasps is the giant scoliid of Indonesia, Megascolia procer. The smallest wasps are solitary chalcid wasps in the family Trichogrammatidae, some of which are just 0.2 millimetres (0.008 in) in length.
Wasps make up an enormously diverse array of insects, with some 30,000 identified species. We are most familiar with those that are wrapped in bright warning colour one that buzz angrily about in groups and threaten us with painful stings.
But most wasps are actually solitary, non-stinging varieties. And all do far more good for humans by controlling pest insect populations than harm.
Wasps play many ecological roles. Some are predators, whether to feed themselves or to provision their nests. Many, notably the cuckoo wasps, are kleptoparasites, laying eggs in the nests of other wasps. With their powerful stings and conspicuous warning colouration, often in black and yellow, wasps are frequent models for Batesian mimicry by non-stinging insects, and are themselves involved in mutually beneficial Müllerian mimicry of other distasteful insects including bees and other wasps.
