Chilades lajus

Chilades laius

A species of Jewel blues

Wet-season form: Male has a bluish-purple upperside. Forewing has base and basal half of costa flushed with pale blue; costa and termen edged by a slender dark brownish-block even line, beyond which along the termen the cilia are brown, at base, white outwardly. Hindwing: costa somewhat broadly dusky black; a slender black conspicuous anteciliary line, beyond which the cilia are white traversed medially by a brown line; dorsum broadly pale brown, two subterminal pale-bordered black spots in interspace 1, and one similar spot in interspace 2, often obsolescent and barely indicated. Underside: grey. Forewing: a transverse broad lunule on the discocellulars and a transverse discal series of six spots dark brown, the lunule and each of the discal spots edged with white; the posterior four spots of the discal series elongate and each obliquely placed, the anterior two round and curved inwards; a subterminal series of transverse elongate spots with an inner series of lunules dusky brown, both series edged inwardly and outwardly with white; finally, an anteciliary slender black line. Cilia white, medially traversed by a dark brown line. Hindwing: the following jet-black spots slenderly encircled with white: a transverse subbasal series of four and a subcostal spot somewhat larger than the others in the middle of interspace 7; below the latter a catenulated (linked like a chain) line of slenderly white-edged dusky-brown spots, including the lunular spot on the discocellulars, crosses the wing, and beyond these opposite the apex of the cell are three similar discal spots, the middle one elongate; the terminal markings consist of an inner continuous subterminal series of dusky lunules, bordered inwardly and outwardly with white, an outer subterminal series of inwardly conical dusky-brown spots, and a slender anteciliary black line. The posterior two spots of the outer line of subterminal markings are also black. Cilia white. Antennae black, the shafts obscurely ringed with white; head, thorax and abdomen brown, the head, thorax and base of the abdomen with a little blue scaling; beneath: the palpi, thorax and abdomen white. Female upperside: dark brown. Forewings and hindwings from their bases outwards to a varying extent shot with bright iridescent blue, this colour not extended on either wing to the costa, termen or dorsum. Hindwing: in addition a curved postdiscal series of whitish lunules very often obsolescent, in some specimens entirely wanting; followed by a subterminal series of black, narrowly white-encircled spots that are often obscure and in some specimens do not reach the apex. Anteciliary black lines and cilia as in the male. Underside: precisely similar to that of the male. Antennae, head, thorax and abdomen as in the male. Dry-season form: Closely resemble specimens of the wet-season brood, but can always be distinguished by the somewhat paler ground colour of the upperside, while on the underside both sexes bear a large nebulous brown patch on the hindwing posteriorly. Sometimes the ground colour on the underside is much paler, almost white, especially in the female.

Life Cycle of Chilades lajus
Egg The chilades lajus begins as an egg, often laid on plants. The egg is tiny, spherical, and varies in color. It serves as a protective case, nurturing the developing larva.
Larva Once hatched, the larva of chilades lajus consumes plant material voraciously. It is elongated, with distinct segmentation and a different color pattern compared to the adult, aimed at camouflage.
Pupal The larva transforms into a pupa. This stage remains immobile attached to a substrate. The chilades lajus is encased within a chrysalis, undergoing significant internal restructuring.
Adult Emerging from the pupa, the adult chilades lajus’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Chilades lajus
There is no specific trap food recommended, as chilades lajus is not typically lured using bait. Instead, identifying host plants and natural habitats is more effective.
Rectangle
Habitat Preferences of Chilades lajus Through Different Life Stages
The eggs of chilades lajus are typically deposited on the undersides of host plant leaves. Caterpillars, once hatched, are found on or near the host plants, consuming leaves and growing through several instars. Pupae are often well-camouflaged and attached to stems or leaves of the host plants. Adults inhabit open grassy areas, edges of forests, and gardens where they feed on nectar. If seeking these stages, one would inspect host plants for eggs, search foliage for caterpillars, look for pupae on stems or under leaves, and observe adults near flowering plants in sunny, open habitats.
Rectangle
When is the Best Time to Observe Chilades lajus
The suitable time for finding chilades lajus largely depends on its life cycle and local climate, but generally, adults are active during sunny and warm days, while early stages should be looked for during the expected breeding season.
Rectangle
What is the Best Weather to Observe Chilades lajus
Warm and sunny weather is typically most suitable for observing chilades lajus adults, as they are more likely to be active, flying, and nectaring. Overcast days might also be suitable for finding resting individuals.
Rectangle
How and Where Can You Find Chilades lajus at Different Life Stages
Egg Chilades lajus eggs are often laid singly or in small clusters on the host plants, usually on the underside of leaves or near buds. To find them, inspect the host plants carefully, using a magnifying lens if needed.
Larva Chilades lajus larvae can be found on or near their host plants. Search for signs of feeding, like chewed leaves, and look for the caterpillars camouflaged amongst the foliage.
Pupal Chilades lajus pupae may be attached to the host plant or other structures nearby, such as twigs or under leaves. Look for the chrysalis by searching around the larva's last known feeding area.
Adult Chilades lajus butterflies are best found by looking for them as they fly in search of nectar or mates during warm, sunny weather. Visit flowers, especially those native to the area, since adults frequently feed on nectar.

Pollination Behavior Reason
Collect Pollen To Feed Offspring
Chilades lajus are known to participate in pollination while they are on a quest for nectar and pollen. While the adults may feed on pollen, they primarily collect it to feed their offspring. During the process of visiting various flowers, chilades lajus inadvertently transfer pollen, thus fulfilling their role as pollinators. They are attracted to flowers by their vibrant colors and intriguing shapes, playing a pivotal role in the ecosystem.

Boisduval's blue
Boisduval's blue

Larvae of boisduval's blue are extremely small and rarely seen. The males' top wing grades from ice blue in the center to deep sky blue, exhibiting a dazzling iridescent fluctuation in range under direct, full sunlight. Black margins on the upper wing sport long, white, hair-like scales. A constellation of jet-black dots frames the extremities of the ventral surface, its pattern adroitly complementing the wing shape and throwing it into spectacular relief against the shimmering silvery pearlescent background. A fascinatingly muted hint of dark ice blue bleeds faintly up from the body, permeating the veins throughout for the palest, most delicate emphasis. The body shape, eyes, antennae, and appendages give it a uniquely exquisite poise. The males' bodies are dark-blue or brown. The females' upper wings are dark brown but otherwise mirror the males'.

Icaricia icarioides missionensis
Icaricia icarioides missionensis

The endangered Mission blue has a wingspan around 21–33 millimetres (0.83–1.3 in). Larvae are extremely small and rarely seen. The males' top wing grades from ice blue in the center to deep sky blue (misregistered as turquoise/cyan to violet by most photographic equipment, the wing color carries no hint of green or purple, strictly capturing an enthralling spectrum of purest, clearest, richest, brightest blue) exhibiting a dazzling iridescent fluctuation in range under direct, full sunlight. Black margins on the upper wing sport "long, white, hair-like scales". A constellation of jet-black dots (misregistered as dull gray by most photographic equipment) frames the extremities of the ventral surface, its pattern adroitly complimenting the wing shape thrown into spectacular relief against the shimmering silvery pearlescent background, with a fascinatingly muted hint of dark ice blue bleeding faintly up from the body and permeating the veins throughout for the palest, most delicate of emphases. Body shape, eyes, antennae, and appendages possess it of a uniquely exquisite poise. The males' bodies are dark-blue/brown. Females' upper wings are dark brown, but otherwise mirror males'. The larvae only feed on the leaves of the three host lupine plants (Lupinus albifrons, Lupinus formosus, and Lupinus variicolor) native to their habitat. The plants are necessary for survival for the Mission blue. Thus, the butterfly's fate is closely tied to that of the three species of lupines as the plants provide food and shelter for the butterfly in its larval stage. The adult Mission blue drinks the nectar of a variety of flowers, many in the sunflower family, using its long proboscis which extends from the underside of its head.

Southern Brown Argus
Southern Brown Argus

In specimens [ of astrarche ] from the Canaries the red macular band of the upperside is occasionally quite uncommonly broad and of even width, so that it forms a regular band, only transected by the black veins; this is ab. cramera Eschsch. (= canariensis Black.) (80 a). I also caught very extreme specimens of this form on the slopes of the Aures Mts. in Algeria, although only singly; on the other hand I met on the Canaries with specimens of astrarche which certainly did not belong to cramera, but rather to calida.
