| Pterourus troilus (Linnaeus, 1758) |
| Status: Rare stray. |
| Flight Period(s): Multiple flights in its home range. It likely does not breed in Nebraska except on ornamentals. |
| Range: The Spicebush Swallowtail is a resident in the southern and eastern United States from eastern Texas to the New England states. From there it strays north to the Canadian border. In Nebraska it has been found in the southeastern quarter of the state. |
| Larval Hostplant(s): Ornamental laurels - Spice bush (Lindera benzoin) and sassafras (Sassafras species). |
| Overwinter: In its home range this species overwinters as pupae, but is not thought to do so in Nebraska. |
| Commentary/Habitat: It is a resident of wooded areas in its home range, but as a stray it might be encountered anywhere here. The two most recent records are from Wilderness Park in Lincoln (18 July 1998 – Steve Spomer) and from LaVista (17 June 2001 – Jim Reiser). This swallowtail is another mimic of the distasteful Pipevine Swallowtail. |
