Photo Life History: Papilio eurymedon Intermountain segregate
Suitable Lab Host Plants:
Caring for Live Female Butterflies: Feed females every day.
Methods of Female Oviposition: The open screen cages slide show demonstrates how this is accomplished for glaucus-group females, which, can be quite uncooperative for a few days when it comes to laying eggs in captivity. It's important to set them up in a cage where there is plenty of room to fly to and from the host plant. Also, provide nectar sources for females. Clark Thompson created a successful setup for California Papilio rutulus.
How to Find Eggs: Because the larval host plants of pale swallowtails are trees and shrubs, it is always wise to look for immatures on isolated host plants, if at all possible. Also, try and look on plants where you know adults fly well. Population numbers of this butterfly can fluctuate due to predation, parasitism, and other factors.
How to Hatch Eggs: Consolidate eggs into one container.
How to Find Caterpillars in the Field: For earlier instars, look on the dorsal side of the leaf. For later instars, look for swallowtail pads. Finding glaucus-group caterpillars in numbers can be difficult and sometimes requires a certain degree of patience and hard work.
Number of Broods per Year: 1-3; depending upon location
Overwintering Stage: Pupa.
Avoiding Diapause Techniques: Not applicable.
Disease Prevention: Change out host plant and remove frass every five to six days using the open terrarium technique.
Emergence: Emergence Container
