Dusky large blue

Dusky large blue

Phengaris nausithous

A species of Phengaris

Adorned with a palette of earthy hues, dusky large blue is a sight to behold as it flutters across meadows, its undulating flight pattern a dance with the wind. With an intricate relationship to a particular ant species in its larval phase, this remarkable insect has evolved a form of chemical mimicry that allows it to integrate seamlessly into ant colonies, a strategy that protects it until metamorphosis. The curious life cycle of this species echoes the complex interdependence found within the ecosystems it inhabits.

Life Cycle of Dusky large blue
Egg Spherical or ovate, the eggs of dusky large blue are often laid on plants. They are tiny and may vary in color, usually mimicking the plant to avoid predation.
Larva Known as caterpillars, dusky large blue larvae possess a segmented body with a distinct head, chewing mouthparts, and several pairs of legs. They exhibit rapid growth, molting several times.
Pupal Dusky large blue undergoes pupation within a chrysalis. During this stage, transformation occurs, with internal reorganization from larval to adult structures, typically attached to foliage or debris.
Adult The adult dusky large blue emerges with developed wings, exhibiting vibrant colors and patterns for mating displays. They possess functional reproductive organs, seeking mates to reproduce.

How Can You Attract Dusky large blue
For adults, sweet substances like rotting fruit or sugary solutions can serve as bait. For larvae, Myrmica ant nests are essential.
Rectangle
What is the Best Weather to Observe Dusky large blue
Look for adults on sunny days with little wind, which are optimal for butterflies' flight. Wet weather can be suitable for finding larvae inside ant nests.
Rectangle
How and Where Can You Find Dusky large blue at Different Life Stages
Adult Dusky large blue can be found in meadows with abundant flowers. Searching during sunny weather when butterflies are most active will increase the chances of sighting.
Larva Dusky large blue larvae live inside the nests of Myrmica ants. Look for these ant nests in areas with low vegetation and gently inspect them to find the larvae without disturbing the nest.
Pupal Dusky large blue pupae will be within Myrmica ant nests, making them difficult to detect. Search for ant nests that the larvae are associated with and carefully observe for any pupal cases.
Egg Look for dusky large blue eggs on the underside of host plant leaves, which are typically specific species of flower. These are laid singularly, so searching meticulously is necessary.

Pollination Behavior Reason
Eat Pollen Or Nectar
Dusky large blue is an effective agent of pollination, flitting from flower to flower in search of nectar. In the process, it inadvertently gathers and transfers pollen, aiding in the fertilization of plants. It is attracted to flowers by their vivid colors, alluring scents, and intriguing shapes, and while consuming pollen, it plays a crucial role in the reproductive cycle of flowering plants.

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'.

Lupine Blue
Lupine Blue

Icaricia lupini, the lupine blue, is a butterfly of the family Lycaenidae. It is found from south-western Canada, south through much of mountainous and intermountain western United States and high plains to northern Mexico. The wingspan is 22–29 mm. Adults are on wing from June to August in one generation in the Sierra Nevada of eastern California. Elsewhere, there are several generations from March to July. The larvae feed on Eriogonum umbellatum and Eriogonum fasciculatum. Adults feed on flower nectar. The hairs of the caterpillars can cause skin irritation (urticaria).

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.

Eumedonia eumedon
Eumedonia eumedon

Endemic to specific ecosystems, eumedonia eumedon exhibits a remarkable adaptation in its larvae, which engage in a mutualistic association with ant species. These larvae secret a sweet substance that attracts ants, which in return provide protection against predators. The adult form is known for its striking wing patterns that serve as a visual deterrent to potential threats and plays a role in intraspecific communication during the breeding season.

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.

The monarch butterfly (Danaus plexippus) is the most recognizable butterfly in North America. It is best known for its appearance, but should be better known for the fact that it has a 3000-mile migration that takes the butterfly 4 generations to complete. Their diet is also a natural deterrent for predators, as they eat milkweed, a poison that induces vomiting.
