Consider the Data in Figure 46 B

question 60

Short Answer

Consider the data in Figure 46.11 illustrating the survivorship curve of the lime swallowtail butterfly. As indicated in your text, the survivorship from the egg to larval stage is 68%. If the average time from egg to adult is 43 days, what is the per capita death rate? a.
$\begin{array} { l l l l } \text { Stage } & \text { Approximate duration } & \text { Number alive } & \text { Survivorship } \\ \text { Egg } & 5 \text { days } & 250 & 0.68 \\ \text { Larva } & 18 \text { days } & 170 & 0.93 \\ \text { Pupa } & 15 \text { days } & 158 & 0.45 \\ \text { Adult } & 5 \text { days } & 71 & \end{array}$
