Sampling description

Diverse methods for collecting and observing have been used. Most data, however, is from light trapping throughout season in a fixed location. All Macrolepidoptera have been identified and counted. Absence can be inferred from lack of record. Microlepidoptera have been identified where possible, but their numbers are not necessarily quantitative, and lack of record does not mean absence.

Method Steps

  1. Light traps and bait traps of various kinds have been used. They have been checked at various intervals. One can count organismQuantity per day by dividing individualCount with eventDate range. Specimens have been preserved from some observations. Coding of basisOfRecord is as follows: Monitoring = Quantitative sample where all Macrolepidoptera individuals have been counted, and lack of record means absence. Microlepidoptera have been processed on best efforts basis as Observations (as below). Observation = Sample which is not quantitative, but where all individuals were examined. Sighting = Live individuals seen in the field. Specimen = has been retained for evidence. Note that there can be multiple Specimens saved for Observation or Monitoring records. In the Specimen record, such a parent record has been linked through associatedOccurrences. There are a few variants of these, for instance when preparates have been made of specimens.
