Description and Characteristics

The Tiger Swallowtail Butterfly (Papilio glaucus) is characterized by its large wingspan, striking yellow and black coloration, and distinctive tail-like extensions on its hindwings.

Belonging to the family Papilionidae, this species exhibits sexual dimorphism, with females sometimes displaying a darker morph. Adult wingspans range from 8.9 to 14 cm, making it one of the larger North American butterflies.

The body is robust, with a black thorax and abdomen adorned with yellow spots. The forewings are elongated and angular, while the hindwings are rounded with 'swallowtails'—prolongations that resemble avian tails.

This butterfly is found in deciduous forests, woodlands, and river valleys, where its larvae primarily feed on the leaves of deciduous trees such as tulip trees (Liriodendron tulipifera) and wild cherry (Prunus serotina).

Color Patterns

Exhibiting a vivid interplay of yellow and black, the wing pattern of *Papilio glaucus* serves both as camouflage and a warning signal to potential predators. This intricate coloration is a hallmark of the species, playing an essential role in its survival. The forewings feature bold black tiger stripes on a yellow background, while the hindwings possess a blue and orange eyespot near the tail, adding to their visual complexity.

• Pattern Symmetry: The wings display bilateral symmetry, enhancing their visual appeal.
• Sexual Dimorphism: Females often exhibit a darker morph, mimicking the toxic *Battus philenor*.
• Adaptive Significance: Color patterns deter predators via Batesian mimicry.

These facets underscore the adaptive significance of their striking color patterns.

Habitat and Range

Papilio glaucus occupies a diverse range of habitats, including deciduous forests, swamps, and suburban gardens across North America. This species, commonly known as the Eastern Tiger Swallowtail, exhibits adaptability to various environmental conditions, thriving in both natural and human-altered landscapes.

Geographically, its range extends from the eastern United States to the Great Plains, and from the southern parts of Canada down to Florida and Texas. The butterfly prefers regions with ample host plants such as tulip trees (Liriodendron tulipifera) and wild cherry (Prunus serotina) for oviposition.

Microhabitat preferences include areas with abundant nectar sources, necessary for adult sustenance. The species' wide range and habitat versatility underscore its ecological resilience and evolutionary success within the Lepidoptera order.

Life Cycle

Understanding the life cycle of *Papilio glaucus* reveals the intricate processes that enable its survival and reproduction across diverse habitats. This species, belonging to the family Papilionidae, undergoes complete metamorphosis, encompassing four distinct stages: egg, larva, pupa, and adult.

• Egg: Females deposit spherical eggs on the leaves of host plants, ensuring offspring have immediate access to food upon hatching.
• Larva: Caterpillars, initially resembling bird droppings for camouflage, undergo several molts, growing and developing distinct coloration.
• Pupa: In this stage, the larva forms a chrysalis, undergoing significant morphological changes within a protective casing.

This cyclical process underscores the adaptability and resilience of *Papilio glaucus*.

Feeding Habits

The feeding habits of Papilio glaucus, commonly known as the Tiger Swallowtail Butterfly, are characterized by their preference for specific nectar sources.

These butterflies primarily feed during daylight hours, favoring flowers from families such as Asteraceae and Apocynaceae.

Their proboscis is adapted for extracting nectar from tubular flowers, including species like Asclepias, Buddleja, and Lantana.

Nectar Sources

Tiger Swallowtail butterflies (Papilio glaucus) primarily derive their sustenance from the nectar of flowering plants, exhibiting a marked preference for species within the genera Buddleja, Lantana, and Asclepias.

These lepidopterans utilize their proboscis, a specialized feeding organ, to access the nectar deep within floral structures. Nectar sources play a significant role in their energy intake, aiding in flight, reproduction, and overall survival.

The following plants are particularly favored by P. glaucus:

• Buddleja (commonly known as butterfly bush)
• Lantana (vibrant clusters of small flowers)
• Asclepias (milkweeds, important for various pollinators)

Understanding these nectar preferences is essential for conservation efforts and habitat preservation, ensuring these butterflies thrive in their natural environments.

Feeding Times

In addition to their nectar preferences, Papilio glaucus exhibits diurnal feeding habits, primarily foraging during daylight hours when floral nectar is most abundant and accessible.

This temporal feeding strategy aligns with the butterfly's physiological need for light and warmth to optimize metabolic processes. Diurnality in the Eastern Tiger Swallowtail allows it to exploit the peak periods of nectar availability, essential for sustaining its energy-intensive flight.

Observations indicate that feeding activity is most intense during mid-morning to early afternoon. The species demonstrates a preference for sunny, warm conditions, as these environmental factors enhance the visibility and accessibility of nectar sources.

Such behavior underscores the intricate relationship between Papilio glaucus and its habitat, reflecting adaptive strategies for survival and reproduction.

Preferred Flowers

Papilio glaucus frequently exhibits a marked preference for nectar from Lantana camara, Asclepias tuberosa, and Buddleja davidii, which provide essential nutrients for its energy demands. This Lepidoptera species relies on these floral resources to sustain its high metabolic rate during flight and reproduction. The selection of these flowers is influenced by factors such as nectar composition, floral morphology, and availability.

Key preferred flowers include:

• Lantana camara: Provides abundant nectar and vibrant coloration.
• Asclepias tuberosa: Offers high nectar yield and attracts a diverse pollinator assemblage.
• Buddleja davidii: Known for its elongated inflorescences, facilitating efficient feeding.

These preferences underscore the butterfly's adaptive feeding strategies and ecological interactions.

Behavioral Traits

The behavioral traits of the Tiger Swallowtail Butterfly (Papilio glaucus) exhibit distinct patterns of feeding, mating, and territoriality that are vital for its survival and reproduction.

Papilio glaucus engages in nectarivory, primarily consuming nectar from Liliaceae, Apiaceae, and Fabaceae families.
