literally hundreds ofAnartia over the course of five days, not a single egg was found on the host plants. After the experiment was complete, the researcher began to compare the north central Florida test versus the Costa Rica test in order to reason why there was such a drastic difference in oviposition levels. There was indeed one glaring difference between the trials. In both north central Florida and Costa Rica, orange marking flags were used to delineate transects and mark the experimental host plants. It could have been possible that Monarch females saw the orange marking flag and were attracted to it as being a possible mate, subsequently ovipositing on the plant, or returning at a later time to oviposit. At this point, shiny blue plastic material was used to mimic butterfly presence in the same way the orange flags were presumed to do. After the blue plastic was tied to the host plants, the 10-day experiment was repeated (Figure 4-7). Again, there was no oviposition. Although the orange marking flags could have served as an attractant in the north central Florida trials, there is no proof. This brings us to the question of why Monarch butterflies were the only species that oviposited during the north central Florida trials? Although Swallowtails and Buckeyes were seen regularly in and around the farms, there was virtually no oviposition (there were two eggs seen of the Swallowtail during the entire experiment). There are two main factors believed to be the cause for this lack of oviposition. The first is a relative lack of visual conspicuousness. Courtney (1982) suggested that the level of visual conspicuousness (i.e., how obvious a plant is compared to its surroundings) directly affects oviposition in butterflies. Specifically, as visual conspicuousness increases, so does oviposition. Based on the size, color, and leaf shape of the two host plants used for the Swallowtail and Buckeye (parsley and plantain, respectively), they likely exhibited a relatively low level of visual conspicuousness in relation to their surroundings.
