Couverture géographique

Fiji (17.7134° S, 178.0650° E) is a group of volcanic islands in the South Pacific. The group of the volcanic island comprises of about 330 islands in which a 100 of this islands are permanently inhabited. The data covers Fiji’s main islands namely Viti Levu and Vanua Levu, a few of Fiji's smaller islands as well as the Polynesian island of Rotuma.

Couverture taxonomique

There are about 400 species of Macrolepidoptera recognized to occur in Fiji and Rotuma which are noted and described: however, few species remain unplaced. Taxonomic treatment has included amendment of names, the establishment of new combinations and formation of new names. Most species are explained, many species are redescribed with respect to its life history and distributional information provided where this is recognized. The taxonomic families included in this data set includes about 19 families of macro moths.

Couverture temporelle

Données sur le projet

The data focuses on transcribing and updating taxonomic names for Gaden Robinson's record from 1970's on macro- moth's located in Fiji and Rotuma.

Méthodes d'échantillonnage

The collection and recordings were obtained through Mercury-vapour light traps. From 1970 to 1972 a total of 36,183 Macrolepidoptera were recognized and tallied from 109 one-night MV trap samples.

Description des étapes de la méthode:

1. Between 1966 and 1970 Robinson used a mercury vapor light trap to exclusively collect Lepidoptera. The collection was restricted to certain localities in Viti Levu (unless otherwise stated). The trapped was used in the Suva garden, occasionally at Savura Creek (water pumping station-1km W of Tamavua) in a low land forest. The trap was also set in Colo-i-Suva (J.W.Parham’s house). Traps were also placed at Nadarivatu at the Forestry Dept. rest house and at a radio station at South Rim. Species were briefly collected at Lautoka, Rakiraki, and Korolevu (near Namaqumaqua), Nananu-i-Ra as well as in Savusavu, Vanua Levu. In December 1969, the author placed traps at four sites in Nausori Highlands, east Nadi. It was estimated to have collected between 0.8 and 1 million Lepidoptera in 200 nights in which 50% were Macrolepidoptera. From the limited fieldwork till 1970, the author decided to use Robinson’s pattern MV light trap operated with either with the usage of main electricity or a portable generating set. This was used to collect rare species and other Lepidoptera species in higher preference within a short distance (20m) of the trap. Thus, this trapping programme was to use which involved 2 very similar types of Robinson MV trap only differing with the construction of the barrel. The barrel was lined with a cotton bag which could be detached with the catch. The anesthetic evaporator was placed between the bag and the barrel. Tetrachloroethane is known to be the only apt anesthetic for light traps and liable on the locality, the author used either an evaporator with a long cotton wick or an electrically heated evaporator. For the duration of the fieldwork, the barrel was used as an all-purpose vessel. In areas where 240v. AC mains electricity was unattainable, a Honda E300 portable generator was used to provide power- The light source was a 125w. MV lamp with frosty globe: the electrical circuit comprised of a choke and 15 µF capacitors for power-factor adjustment. Light traps were emptied in the morning as early as possible and usually, the catch was deeply anesthetized or dead at this stage. Where possible, the catch was dealt with straightaway into distinct species and the numbers of each species counted and recorded.
