Flight Intercept Traps, Feb-Mar 2004
Flight-intercept samples were taken from February to March 2004 to parallel similar sampling taking place at the 300m site (Cantarrana) on the Barva transect. Ten plastic trays were placed beneath the center pane of a Malaise trap (Figure). Soapy water was placed in the trays. Trays were checked daily. Each day specimens were netted from the trays and accumulated in a bottle of 95% ethanol. Sampling was carried out to parallel the sample accumulating in the collection head of the Malaise trap. One sample comprised two-weeks of accumulated specimens. On harvest, samples were transported to the ALAS lab, the ethanol was changed once, and samples were stored in a freezer. Samples are listed below.
The data fields, in order, are:
Collection code: a unique code for a collection. The "TN" indicates it is a flight-intercept sample, the following two numbers are the trap number, and the final three-digit number is a serial number beginning with 001 for the first sample and ending with 030 for the last sample. In addition, there is a code for all flight intercept samples pooled.
First collection date: First day of the sample period, in format day-month-year.
Second collection date: Day the sample was harvested.
X and Y coordinates: La Selva GIS coordinates.
