Butterflies of Singapore and Peninsular Malaysia (Lycaenidae)

Study Extent

Currently there is scant information on the sampling methods due to the idiosyncretic sampling nature undertaken by the various collectors.

Sampling

Active sweep net collecting is the most common method for collecting butterflies, although some forms of baited traps are also employed for certain groups of butterflies.

Quality Control

Quality control for this project occurs at the data capturing and data processing stages. Incomplete information that requires certain level of interpretation were conducted with annotated remarks or verbatim data for further verification. Georeferencing data added were given a conservative level of uncertainty.

Method steps

1. Label information were first transcribed onto Excel sheets as one of the first steps of data mobilization. Event Date interpreted from verbatim date from original label. Georeferencing was conducted based on a consolidated list of unique localities. GPS coordinates were estimated post hoc using Google Earth, with verification with original collector where possible. Image association is also performed using the Excel sheet by adding the url link to each specimen after the images of the specimens were uploaded to a separate image hosting server. Image filenames were interpreted by an OCR algorithm using catalogue number label within the image taken.
   Dataset cleaned using OpenRefine and saved as csv file for uploading.

This dataset consists of Lycaenidae butterflies found in Singapore and Peninsular Malaysia. All butterflies are identified to species or subspecies.
