Flowers visited Palpada vinetorum has been seen visiting the flowers of 14 plant species in 12 families: Emilia fosbergii Nicolson , Sphagneticola trilobata (L.) Pruski, Tridax procumbens L. ( Asteraceae ), Heliotropium foertherianum Diane & Hilger (Boraginaceae) , Weinmannia vescoi Drake (Cunoniaceae) , Euphorbia fosbergi (J.Florence) Govaerts (Euphorbiaceae) , Hyptis capitata Jacq. (Lamiaceae) , Geniostoma clavatum J.W.Moore (Loganiaceae) , Pemphis acidula J.R.Forst. & G.Forst. (Lythraceae) , Bougainvillea sp. ( Nyctaginaceae ), Ludwigia octovalvis (Jacq.) P.H.Raven (Onagraceae) , Portulaca oleracea L. cv. Wild Fire ( Portulacaceae ), Gardenia taitensis DC. ( Rubiaceae ) and Lantana camara L. ( Verbenaceae ). Three of these plants, i.e., W. vescoi , E. fosbergi and G. clavatum , are endemic to French Polynesia . Genetics The BOLD Process IDs for the DNA barcodes (5′– COI ) for this species are: SYC2574-14 (= KX054301 , specimen symbiocode_02652), SYC2867-14 (= KX054303 , specimen symbiocode_ 02946), SYC5397-14 (= KX054299 , specimen symbiocode_05482), SYC5403-14 (= KX054302 , specimen symbiocode_05488), SYC5438-14 (= KX054298 , specimen symbiocode_05523), SYC9601- 14 (= KX054300 , specimen symbiocode_09742) and SYC9602-14 (= KX054304 , specimen symbiocode_09743). The Barcode Index Number ( BIN ) for these specimens is BOLD:AAY9710 (https://doi.org/10.5883/BOLD:AAY9710). References Thompson 1989: 16 (cit., records); Thompson & Vockeroth 1989: 451 (catalogue). Remarks Thompson (1989) reported this Neotropical species for the first time in the south Pacific Region and estimated a very recent introduction to this archipelago. The first records date back to 1984 and were from Moorea.
