ALAS Light-trap Collections, 2001 Expeditions

Entotech light traps were used to obtain a series of one-night blacklight samples. These traps use a 8 watt blacklight tube surrounded by 3 transparent panes, all perched over a funnel on top of a bucket. The bucket has an internal smaller funnel and screen to allow water drainage from rain. Unlike the La Selva sampling program, the traps were not surrounded by a larger wire cage to exclude large insects. Crumpled paper towels and egg cartons were placed in the bottom of the bucket, and a cloth bag of potassium or sodium cyanide suspended inside. The traps were placed before dusk and harvested the next morning. A light sensor turned the light on at dusk and off at dawn.

During the first week of the first expedition, Marc Epstein ran traps in several locations. At the end of his visit, two sites were chosen, and traps were placed in those two fixed sites each night (see map). Samples are listed below.

Abundant collecting was also carried out at a mercury vapor lamp. A sheet was tacked to the side of the refuge building, and the lamp suspended in front of the sheet. The lamp was usually operated from nightfall until 9 or 10pm, and collectors hand-picked from the sheet. No quantitative sampling structure was applied to mercury vapor lamp collecting. Each collector obtained their own specimens and assigned their own collection codes.

The data fields, in order, are:

Collection code: a unique code for a collection. The "11" indicates that it is from the 1070m site, the "L" indicates it is a light-trap sample, the following two numbers are the trap location ("00" for various trial locations, "01" and "02" for the two fixed locations; see map), and the final three-digit number is a serial number beginning with 001 for the first sample, and ending with 070 for the last.

Collection date
: day sample was harvested (morning following trap placement), in format day-month-year.

Collector: person taking the sample, Marc Epstein for early samples, ALAS staff for later samples.
