The fate of primary-dispersed Mauritia flexuosa L.f. fruit in different microhabitats in the Aripo Savanna Environmentally Sensitive Area, Trinidad, West Indies

Linton L. Arneaud — 2024-04-21

The fate of 1,500 Mauritia flexuosa L.f. fruit was observed between three distinct microhabitats of the Aripo Savanna Environmentally Sensitive Area, in Trinidad, by situating fruit stations and monitoring fruit fortnightly. Most fruit were used as a food source, with the most common fruit fate in all microhabitats being seeds remaining with the mesocarp partially or totally removed. Seed dispersal mainly occurred in the closed canopy of eastern forest margins and was negligible in island microhabitats (where stands of trees are surrounded by savanna). A lack of seed dispersers does not seem to be an immediate concern; however, ecological managers should closely monitor dispersers and their scatter-hoarding activities.

More than 100 new records of moths and butterflies (Lepidoptera) from Tobago, West Indies, with a new synonym in Crambidae

Matthew J.W. Cock — 2024-05-18

Details of six new butterfly and 128 new moth records from Tobago are presented, including species of Batrachedridae (1), Castniidae (1), Crambidae (20), Erebidae (49), Euteliidae (1), Geometridae (15), Hesperiidae (2), Immidae (2), Lasiocampidae (1), Lycaenidae (2), Noctuidae (12), Notodontidae (11), Nymphalidae (1), Oecophoridae (3), Pyralidae (7), Riodinidae (1), Sesiidae (2), Sphingidae (1), Tineidae (1) and Uraniidae (1). Three of the new butterfly records are based on voucher specimens, but the other three and all the moths are based solely on photographs from life, and representative images are included as vouchers. A duplicate record of Hedylidae is pointed out, previously overlooked records of Gelechiidae and Saturniidae are added, the previously unrecognized female of Metria sp. nr. demera Schaus (Erebidae) is associated with the male, and Hemiceras egregia Dognin (Notodontidae) is newly identified. The total number of Lepidoptera species known from Tobago is now 653 moths and 165 butterflies. All newly reported species except four are also known from Trinidad (although some have not been previously published as from Trinidad). Species associated with economic crops include Batrachedra nuciferae Hodges (Batrachedridae), Haritalodes pharaxalis (Druce), Maruca vitrata (Fabricius) and Palpita persimilis Munroe (Crambidae), Cerconota anonella (Sepp) (Oecophoridae), Rupela albina Becker & Solis (Pyralidae), and Eichlinia pulchripes (Walker) (Sesiidae), while Achroia grisella (Fabricius) (Crambidae) and Galleria mellonella (Linnaeus) (Pyralidae) are pests of honeybee hives. Leucochroma analytica Dyar, 1914 is a new synonym of Leucochroma trinitensis Rothschild, 1912.

Matthew J.W. Cock — 2024-04-21

Information and illustrations are provided regarding the 37 species of Nolidae moths now known from Trinidad, and eight known from Tobago (22% of Trinidad total). Eleven genera and five subfamilies are known from Trinidad & Tobago: Afridinae (1 species), Diphtherinae (2 species), Collomeninae (12 species), Eligminae (7 species), Nolinae (15 species). Before 2017, only five species of Nolidae had been recorded from Trinidad & Tobago, seven have been recorded since then, and 25 species are here recorded from the country for the first time

Fruit baits at night attract unusual erebid moths (Lepidoptera) in Trinidad, West Indies, with two taxonomic changes in Erebidae, Herminiinae

Rainer N. Deo — 2024-04-21

Several different fruit baits that were ripened, rotting or fermenting were used to attract moth species belonging to the family Erebidae. Several of these species are considered rare or had not been previously reported for Trinidad. Rejectaria olivenca Goldstein has not previously been recorded for the island. Gigia stenogaster (R. Felder & Rogenhofer) and Hemeroblemma mexicana (Guenée) had previously been observed but their presence on Trinidad had not yet been reported in the literature. The first female specimens of Argania pilosa (Druce), Hemeroblemma dolon (Cramer) and Hemeroblemma helima (Stoll) are reported for Trinidad. The first male specimen of Gigia obliqua (Walker) is reported for Trinidad. Bleptina aeatusalis Walker, 1859 is transferred to the previously unpublished new combination Oidemastis aeatusalis (Walker), which is already in use on the internet. Sitophora totafusca Kaye, 1901 reinstated species is removed from the synonymy of S. vesiculalis Guenée, 1854.
