The Alcon blue butterfly lays eggs on the marsh gentian, but the larvae leave the plant and migrate to the ground to attract ants. Most researchers, however, find this hypothesis highly unlikely because it is not an evolutionarily stable strategy. Shopping. About. After feeding and growing for four instars, the caterpillars drop to the ground. Illustrative Biome Tour for Classrooms. Phengaris rebeli (formerly Maculinea rebeli), common name mountain Alcon blue,[1] is a species of butterfly in the family Lycaenidae. When the Alcon larva is fully developed it pupates. Like some other species of Lycaenidae, its larva stage depends on support by certain ants; it is therefore known as a myrmecophile. Share. Butterfly Conservation priority: Low European Status: Vulnerable; Caterpillar Foodplants. After the ant brood adopts the FDL, which comprise approximately 25% of the total P. rebeli larvae,[23] the FDL complete growth the following spring and eclose (emerge as an adult from the pupa) in early summer to complete their life cycle. It lays its eggs on the Swiss wildflower Gentiana, where the larva feed until they are fatted, and then roll on the ground waiting to be discovered by ants. alcon. (83 a). This butterfly begins life as eggs laid on leaves of Gentiana cruciata plants. The beautiful and rare Alcon Blue butterfly, Maculina alcon, has a surprising life cycle; for about nine months of the year it behaves like a cuckoo.

(B) Recently emerged caterpillar being carried to the nest by a worker of M. rubra. Group Size & Travel: Minimum of 4 and a maximum of 12 guests plus 1-2 leaders. Genbank common name: Alcon blue NCBI BLAST name: butterflies Rank: species Genetic code: Translation table 1 (Standard) Mitochondrial genetic code: … On detecting a P. alcon larva the wasp enters the nest and sprays a pheromone that causes the ants to attack each other. We found that the Myrmica ant community has changed … See how cameraman Alastair MacEwan filmed the Alcon Blue butterfly. It can be seen flying in mid to late summer. Oškinis, Vytautas (2012). [13] There, the caterpillar releases chemicals which mimic the larvae of Myrmica ants. nigra Wheel, has the males strongly darkened, the females being quite black above. On pupation, the wasp eggs hatch and consume the chrysalis from the inside. Download all free or royalty-free photos and vectors. The Butterfly Defect ongoing project ongoing. It belongs to a large family of butterflies, the Lycaenidae, many of whom have a special relationship with ants. In both stages, a P. rebeli caterpillar is brought into the brood nest; however, in full integration, P. rebeli also achieves its high social status within the host society. Up Next. There are three groups within this Maculinea-Phengaris clade: the alcon group, the teleius group, and the Arion-Phengaris group. The caterpillars hatch and feed upon the flowers and developing fruits of the plant. Once hatched, Maculinea caterpillars feed on floral buds for 10–15 days. ''Phengaris alcon'', more commonly known as Alcon Blue or Alcon Large Blue, is a butterfly of the Lycaenidae family and is found in Europe and Northern Asia. However, they are unlikely to be bivoltine (producing two broods in one season). In an experiment, P. rebeli individuals which consumed ant larvae developed more quickly than those who did not. Color Butterfly T shirt - A23173 Black / Oversize M. May 2021. After 2–3 weeks of feeding on flower heads the caterpillar lowers itself to the ground using a silken thread and awaits discovery by foraging Myrmica ants. P. rebeli caterpillars are polymorphic, having two strategies for living and growing underground: to exist as fast-developing larvae (FDL) or slow-developing larvae (SDL). An Alcon blue butterfly (Maculinea alcon) lays her eggs on marsh gentian (Gentiana pneumonanthe) flower heads. The Alcon Blue Butterfly: a master class in animal deception. We studied changes in the Myrmica host ant communities of the xerophilic form of the ant‐parasitic Alcon Blue butterfly (Maculinea alcon) in four hay meadows in the Bükk mountains of Hungary between 2000–2007 and 2018. [6] I. eumerus attempts to parasitize P. rebeli caterpillars within a Myrmica nest. cecinae Hormuz. The larva generally does not break through the shell on the upperside, so that the holes of empty eggs are not easily noticed. See how cameraman Alastair MacEwan filmed the Alcon Blue butterfly.

An Alcon blue butterfly (Maculinea alcon) lays her eggs on marsh gentian (Gentiana pneumonanthe) flower heads. Size and Family. The larvae emit surface chemicals (allomones) that closely match those of ant larvae, causing the ants to carry the Alcon larvae into their nests and place them in their brood chambers. The species of large blue butterfly we study at the Universities of Copenhagen and Aarhus is the Alcon blue, Maculinea alcon. The Alcon Blue butterfly (Phengaris Alcon) is very pretty, but appearances can be deceiving for it is a rather wicked creature. Once inside the nest, the caterpillar tricks the ants into feeding and caring for it. 2:54.
