Stigmella ilsea is a moth of the family Nepticulidae. [2] It is endemic to New Zealand and has been observed in the North and South Islands. The larvae of this species are leaf miners and feed on Olearia virgata , Olearia rugosa , Olearia odorata , Olearia laxiflora , Olearia lineate and Olearia hectorii . Adult moths have been recorded in January, October and November. Reared specimens emerged from July to September. There is likely one generation per year.

Taxonomy

This species was first described in 1989 by Hans Donner and Christopher Wilkinson from specimens collected in Taupō and Otago. [3] The male holotype specimen, collected at Whenuakura flats at Whanganui Valley in the Taringamotu State Forest at an altitude of 792 m on the 11 October 1979 by J. S. Dugdale, is held in the New Zealand Arthropod Collection. [3]

Distribution

This species is endemic to New Zealand and has been observed in the North and South Islands. [1] [4] [3]

Hosts

Larval host O. virgata.

The larvae feed on Olearia virgata , Olearia rugosa , Olearia odorata , Olearia laxiflora , Olearia lineate and Olearia hectorii . [5]

Behaviour

The larvae mine the leaves of their host plant. The mine starts as very narrow gallery, but a full-grown larva occupies all space between the cuticles, leaving nothing but a small, empty bladder. Larvae have been recorded from February to May and in July and September. The cocoon is pale brown and is spun in detritus on the ground underneath the host plant. Adult moths have been recorded in January, October and November. Reared specimens emerged from July to September. There is probably one generation per year. [3]

<i>Stigmella fulva</i> Species of moth endemic to New Zealand

Stigmella fulva is a moth of the family Nepticulidae. It is endemic to New Zealand and has been observed in the North Island around Mount Taranaki, in the South Island and at Stewart Island. The species' eggs are laid singly but a considerable number may be deposited on the upper surface of one leaf. The incubation period can last from a week to a month depending on climatic conditions. The larvae mine the leaves of their host plants which are all in the genus Olearia. Larvae have been recorded in all months except January, February and June. The cocoon is brown and spun amongst the leaf litter under its host plant. The pupal period has been shown to range from 21 days to 79 days, again depending on climatic conditions. Adults have been observed on the wing January until March and August to December. They are active in the sun about their larval food plant.

This species pupates in a silk cocoon on the ground underneath its host plant. Adults are on the wing most months of year except for March and April. They have been observed flying during the day near their host plant. There are four or five generations per year. This species is regarded as being widely distributed and locally abundant.

<i>Stigmella hamishella</i> Species of moth

Stigmella hamishella is a moth of the family Nepticulidae. It is endemic to New Zealand and has been observed in the South Island. The larvae mine the leaves of Olearia moschata.

<i>Stigmella hoheriae</i> Species of moth

Stigmella hoheriae is a species of moth of the family Nepticulidae. This day flying moth is found in New Zealand in both the North and South Islands. It inhabits native forest.

Larvae feed on Hoheria species such as Hoheria glabrata, Hoheria populnea, Hoheria sexstylosa and Hoheria angustifolia and have been recorded from February to August. The larvae of S. hoheriae are leaf miners. Their mines create blotches on the host plant leaves. S. hoheriae larvae pupate in a silk cocoon on the ground at the base of their food plant. Adult moths have been observed on the wing in February and from July to December. This species is rarely noticed as it is very small and as a result does not tend to attract attention when on the wing.

<i>Agriophara colligatella</i> Species of moth endemic to New Zealand

Agriophara colligatella, also known as the Olearia Skeletoniser, is a moth of the family Depressariidae. It is endemic to New Zealand and is found on both the North and South Islands. This species inhabits native scrub. Larvae feed on the leaves of species in the genus Olearia during the months of November and December. They then pupate amongst the old flowers and leaves of their host plant. Adults have been observed on the wing from August to September but are most common in January. It has been hypothesised that this species overwinters as an adult as it has been observed on the wing in late autumn and early winter. Adults are attracted to light.
