The lychnis (Hadena bicruris) is a moth of the family Noctuidae. It is found in northern and western Europe and Turkey. It has an Atlantic-Mediterranean distribution. In the East Palearctic it is replaced by Hadena capsincola .
This species has dark brown forewings marked with two prominent white-bordered stigmata and a white subterminal line. The hindwings are buffish, darkening to brown towards the margin but with a prominent white fringe. Seitz states - Distinguished from rivularis F. by the absence of the violet sheen; the markings white instead of yellow; the upper stigmata not conjoined; a conspicuous black blotch above inner margin near base; hindwing fuscous. Larva dull brown, with darker dorsal line and oblique subdorsal streaks. [2]
One or two broods are produced each year and adults can be seen between May and September. Flight is from June to July. [4]
The larva feeds on various Caryophyllaceae such as Dianthus , Lychnis , Saponaria and Silene . [5] The species overwinters as a pupa.
H. bicruis is a nocturnal pollinator meaning that it frequents flowers late in the day or at night. [6] [7] Flowers pollinated by moths are often pale in colour, allowing for moonlight to be reflected for easy detection by pollinators. [6] H. bicruris has a specialised nursery pollination system with Silene latifolia . Nursery pollination systems are those where female pollinators lay their eggs on flowers, and as offspring develop, they consume either the plant or the developing ovules or seeds. [8] [9] In this type of pollination system the host plant and pollinator, in this case the moth, are dependent on each other. This relationship can also be considered parasitic as offspring consume seeds, which impacts seed dispersal. It is important to note that this system is not as strong as other nursery pollination systems, and that co-pollinators can alter the interaction between H. bicruris and S. latifolia. [7]
H. bicruris lack the specialised pollination structures that many other pollinators have. [10] [11] [7] Instead, pollen granules catch on their bodies and legs when they come into contact with a flower to feed on nectar. This is otherwise known as passive pollination, where organisms have no specialised collecting or depositing behaviour or structures, but still contribute to pollination. [12] When the moth then visits the next flower, pollen granules may be transferred from the body to the stigma of the receiving plant. Despite the lack of specialised pollination structures, H. bicruris are considered to be the most efficient pollinator of S. latifolia, where both sexes contribute equally to pollination. Although there is a cost to plants by seed predation, this will potentially occur following visitation by a female. Compared to when a male visits the plant, he will only consume the nectar and not have any impact to any part of the plants structure. H. bicruris visit both male and female S. latifolia flowers, and show no preference for flower sex. [13] The efficiency of a pollinator is determined by the number of fruit that are produced following a pollination event. [14] Studies have found in S. latifolia that 80% of visits by H. bicruris resulted in fruit production, with 45% of ovules being fertilised after a singular pollination visit. [13]
Silene is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many Silene species are widely distributed, particularly in the northern hemisphere.
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants. When self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work.
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. Taxonomically, they are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
The Gothic is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is distributed in temperate Eurasia, in the Palearctic realm, including Europe, Turkey, Iran, Caucasus, Armenia, Transcaucasia, Central Asia, Altai Mountains, and west and central Siberia.
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns leading to rewards of pollen and nectar; they may also have an attractive scent which in some cases mimics insect pheromones. Insect pollinators such as bees have adaptations for their role, such as lapping or sucking mouthparts to take in nectar, and in some species also pollen baskets on their hind legs. This required the coevolution of insects and flowering plants in the development of pollination behaviour by the insects and pollination mechanisms by the flowers, benefiting both groups. Both the size and the density of a population are known to affect pollination and subsequent reproductive performance.
Zoophily, or zoogamy, is a form of pollination whereby pollen is transferred by animals, usually by invertebrates but in some cases vertebrates, particularly birds and bats, but also by other animals. Zoophilous species frequently have evolved mechanisms to make themselves more appealing to the particular type of pollinator, e.g. brightly colored or scented flowers, nectar, and appealing shapes and patterns. These plant-animal relationships are often mutually beneficial because of the food source provided in exchange for pollination.
Silene flos-cuculi, commonly called ragged-robin, is a perennial herbaceous plant in the family Caryophyllaceae. It is native to Eurasia and has been introduced to North America.
The grey chi is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is distributed throughout Europe, although it is not present in southern Spain and Greece, as well as northern Fennoscandia. It is also found across the Palearctic including Central Asia, to the Russian Far East but not in Japan.
Silene latifolia, commonly known as white campion, is a dioecious flowering plant in the family Caryophyllaceae, native to most of Europe, Western Asia and northern Africa. It is a herbaceous annual, occasionally biennial or a short-lived perennial plant, growing to between 40–80 centimetres tall. It is also known in the US as bladder campion but should not be confused with Silene vulgaris, which is more generally called bladder campion.
