After lengthy discussions and testing of the current BUGS methodology, Kawakami sensei and I have decided to alter the methods by which we collect insects during our program in 2003/2004. The methods described here do not allow our students to capture representative samples of insects from sample areas. Strongly aerial insects easily evade the net of the student standing over the 1 m2 area, while grasshoppers and crickets jump right past the students responsible for each side of the sample area. The collected sample, therefore, is strongly misrepresentative of insects that might usually be found in the habitat because the only insects collected are stationary and slow-moving ones. Therefore, we are using the following methods for our team's BUGS project. The most notable deviations appear in the manner we propose to capture our insect samples.

Methods for ISA and Takayama Nishi - BUGS Project 2003/2004
Select sites for insect collection: low grass area, high grass area, wooded area, stream side area.
Assign students to teams.
Distribute equipment to teams. Equipment to be used: aerial nets, ground nets, containers, notebooks, field guides, string, stakes, magnifying glasses, pocket field microscopes.
Record weather conditions, temperature, and location information in the project notebooks.
Collect insects and place them in the containers. Students will collect insects by lining up at one end of the sample area and then walking in a line across it while sweeping their aerial nets for insects. This method captures the majority of grasshoppers, crickets, butterflies, moths, and bees within the sample area. After the initial sweep for aerials, the students will return to the sample area and search for ground-dwelling insects within the sample area for a total of 10 minutes.
Count the insects and attempt to make a preliminary classification in the field.
Bring the insects back to the laboratory for further study.
Video and photograph the insects using the USB microscopes.
Use "What's That Insect?" software to further classify the collected insects.
Return insects to the collection sites and release them.
Analyze results.
Post results, locality data, and pictures on the internet.
Visit other websites to assess similarities and differences between results.
