measurement of circumference, the researcher was able to calculate equal distances and equal

angles for the spacing between all rows.

 A total of three species of host plants were used at each butterfly farm, with each

intended to elicit oviposition from a specific species of butterfly. See Table 2-1 for the complete

list of host plants and butterflies. Different species of host plants were used for a different set of

butterflies at the Costa Rica butterfly farm (Table 2-1), but for both north central Florida

locations the same plants were used. To recapitulate, one plant was placed at each 10m transect

for each row and there were nine rows of host plants total. With three different host plants per

farm, each host plant was replicated three times so that there were three rows for each plant.

Each row contained 11 plants, from a distance of zero (adj acent to the epicenter perimeter) to a

distance of 100 meters. Therefore, 99 individual plants were used for each farm.

 Challenges in placing the plant rows presented themselves in the experiment. First, each

farm was situated within 100 meters from a road. Therefore, several plant rows had to cross

these roads at which points the researcher preserved the 10-meter spacing as much as possible.

In the case of Costa Rica, dense jungle made 10-meter spacing difficult with two of the nine

rows, and as a result the angle between them was slightly more acute than the other rows in this

situation (Figure 2-3).

 In the case of the north central Florida farms, the plants were placed on the edges of roads

(Figure 2-4), which caused several transect intervals to be slightly longer than 10 meters.

Another problem with having roads so close to the farm being studied was that several plants

placed near the road were stolen. However, this happened only once, and the plants were able to

be replaced on the following day, thus minimizing the loss of data.
