Introduction: “The Caterpillar” by Hannah Flagg Gould
“The Caterpillar” by Hannah Flagg Gould first appeared in the early nineteenth century in one of her popular collections of moral and devotional verse, where it quickly gained recognition for its gentle didacticism and appeal to young readers. The poem’s enduring popularity arises from its simple yet powerful lesson on compassion, transformation, and the rewards of mercy. Through the caterpillar’s plea—“Don’t kill me!”—Gould dramatizes the moral responsibility humans bear toward even the “humble worm”, insisting that creatures deemed “uncomely to your sight” may later emerge “on splendid wings” as beings of beauty and grace. The poem’s narrative structure—showing the caterpillar’s retreat “to hide awhile” and its eventual reappearance as a butterfly “most beauteous to behold”—cements its message that kindness can yield unexpected blessings. The concluding moral, expressed in lines such as “The lowest reptile at your feet… / May prove the fruit of mercy sweet”, highlights why the poem resonated with nineteenth-century readers: it teaches empathy, humility, and the value of sparing the weak at a time when moral poetry was widely read and admired.
Text: “The Caterpillar” by Hannah Flagg Gould
‘Don’t kill me!’ Caterpillar said,
As Charles had raised his heel
Upon the humble worm to tread,
As though it could not feel.
‘Don’t kill me!’ and I’ll crawl away
To hide awhile, and try
To come and look, another day,
More pleasing to your eye.
‘I know I’m now among the things
Uncomely to your sight;
But by and by on splendid wings
You’ll see me high and light!
‘And then, perhaps, you may be glad
To watch me on the flower;
And that you spared the worm you had
To-day within your power!’
Then Caterpillar went and hid
In some secreted place,
Where none could look on what he did
To change his form and face.
And by and by, when Charles had quite
Forgotten what I’ve told,
A Butterfly appeared in sight
Most beauteous to behold.
His shining wings were trimmed with gold,
And many a brilliant dye
Was laid upon their velvet fold,
To charm the gazing eye!
Then, near as prudence would allow,
To Charles’s ear he drew
And said, ‘You may not know me, now
My form and name are new!
‘But I’m the worm that once you raised
Your ready foot to kill!
For sparing me, I long have praised,
And love and praise you still.
‘The lowest reptile at your feet,
When power is not abused,
May prove the fruit of mercy sweet,
By being kindly used!’

Themes: “The Caterpillar” by Hannah Flagg Gould
• Theme 1: Mercy and Compassion Toward the Weak
“The Caterpillar” by Hannah Flagg Gould emphasizes the moral necessity of showing mercy to beings weaker than ourselves. The poem opens with the caterpillar pleading, “Don’t kill me!” as Charles raises his heel to crush it, highlighting how easily humans can exercise destructive power over the defenseless. Gould reinforces this theme by showing how the caterpillar promises to “crawl away” and return in a form “more pleasing to your eye,” suggesting that kindness, even toward the lowliest creature, yields unexpected rewards. In the final stanza, the butterfly reinforces this moral explicitly: “The lowest reptile at your feet, / When power is not abused, / May prove the fruit of mercy sweet.” Through this direct moral statement, the poem teaches that compassion—especially toward the powerless—enriches both the giver and the receiver.
• Theme 2: Transformation and Inner Growth
“The Caterpillar” by Hannah Flagg Gould explores the universal theme of transformation, both physical and moral. The caterpillar acknowledges its current unattractive state—“I know I’m now among the things / Uncomely to your sight”—but promises that one day it will rise “on splendid wings.” This physical metamorphosis symbolizes the hidden potential within every being, a potential often overlooked due to superficial judgments. The secretive cocoon process—described as taking place in a “secreted place / Where none could look on what he did”—serves as a metaphor for unseen internal growth. By the time Charles sees the “butterfly… most beauteous to behold,” the poem illustrates how patience and time reveal forms of beauty that are not immediately visible.
• Theme 3: Superficial Judgement vs. True Worth
“The Caterpillar” by Hannah Flagg Gould critiques human tendencies to judge based on physical appearance. Charles attempts to kill the caterpillar simply because it looks “uncomely,” showing how outward unattractiveness often leads to dismissal or cruelty. The caterpillar’s promise to return “more pleasing to your eye” exposes the superficial basis of such judgments. When Charles later beholds the butterfly’s “shining wings… trimmed with gold,” the stark contrast emphasizes how initial appearances rarely represent true worth. The butterfly’s revelation—“You may not know me, now / My form and name are new!”—demonstrates that beauty, identity, and value evolve, urging readers to look beyond surface-level impressions.
• Theme 4: Gratitude and Moral Reciprocity
“The Caterpillar” by Hannah Flagg Gould presents gratitude as a noble response to kindness. After transforming, the butterfly returns to thank Charles, saying, “For sparing me, I long have praised, / And love and praise you still.” This moment underscores the idea that good deeds generate positive relationships and lasting appreciation. The butterfly’s acknowledgment that its survival depended entirely on Charles’s choice—“the worm you had / To-day within your power!”—highlights the interconnected nature of actions and consequences. In this way, the poem suggests that acts of kindness cultivate moral reciprocity, where mercy given is eventually returned as affection, beauty, or spiritual reward.
Literary Theories and “The Caterpillar” by Hannah Flagg Gould
| Literary Theory | Explanation & Application to the Poem (with textual references) |
| 1. Moral / Didactic Criticism | “The Caterpillar” by Hannah Flagg Gould is strongly didactic, aiming to teach ethical behavior—especially mercy toward the weak. The poem ends with a clear moral: “The lowest reptile at your feet, / When power is not abused, / May prove the fruit of mercy sweet.” This explicit lesson reflects the core of moral criticism: literature as a tool for cultivating virtue. The caterpillar’s plea—“Don’t kill me!”—positions the reader to empathize with the powerless, reinforcing the poem’s pedagogical purpose. |
| 2. Reader-Response Theory | From a reader-response perspective, the poem invites the reader to emotionally engage with the caterpillar’s vulnerability. Lines like “As Charles had raised his heel / Upon the humble worm” evoke discomfort and prompt the reader to reflect on their own behavior toward weaker beings. Different readers may react differently—some might sympathize deeply with the caterpillar, others might reflect on their own experiences of being powerless. The transformation into a butterfly—“Most beauteous to behold”—also shapes readers’ emotional satisfaction, as the narrative rewards kindness with beauty. |
| 3. Ecocriticism | Through an ecocritical lens, the poem positions nature—specifically the caterpillar and butterfly—as possessing intrinsic value and deserving respect. The caterpillar’s voice humanizes non-human nature: “I know I’m now among the things / Uncomely to your sight; / But by and by on splendid wings / You’ll see me high and light!” This speech challenges anthropocentric attitudes and emphasizes the interconnectedness between humans and the natural world. The poem critiques human dominance by showing that even tiny creatures have feelings and contribute beauty to the ecosystem. |
| 4. Structuralism | A structuralist reading focuses on binary oppositions that structure the poem’s meaning. The poem contrasts ugliness vs. beauty (“uncomely… splendid wings”), weak vs. strong (the worm at Charles’s feet vs. the transformed butterfly), power vs. mercy (Charles’s raised heel vs. sparing the worm), and ignorance vs. wisdom (Charles’s initial thoughtlessness vs. the moral lesson he learns). These oppositions form the deep structure of the text, guiding meaning through paired contrasts that culminate in the butterfly’s moral revelation. |
Critical Questions about “The Caterpillar” by Hannah Flagg Gould
1. How does “The Caterpillar” by Hannah Flagg Gould construct a moral argument about the use and abuse of power?
“The Caterpillar” by Hannah Flagg Gould presents a clear ethical critique of how humans exercise power over weaker beings, using the encounter between Charles and the caterpillar as a moral test. The poem opens with Charles raising his heel “upon the humble worm to tread / As though it could not feel,” immediately portraying careless domination rooted in assumptions about superiority. The caterpillar’s plea—“Don’t kill me!”—introduces a counter-argument grounded in empathy, challenging the reader to reconsider the moral legitimacy of harming defenseless creatures. When the butterfly later returns to thank Charles, declaring “For sparing me, I long have praised,” the poem rewards compassionate restraint and highlights the ethical consequences of choice. The closing lines—“The lowest reptile at your feet… may prove the fruit of mercy sweet”—crystallize Gould’s assertion that true power lies not in the ability to destroy, but in the willingness to spare. Thus, the poem uses narrative transformation to argue for humane, conscientious use of power.
2. In what ways does “The Caterpillar” by Hannah Flagg Gould explore the theme of transformation, both literal and metaphorical?
“The Caterpillar” by Hannah Flagg Gould employs metamorphosis not only as a biological event but as a metaphor for moral, aesthetic, and spiritual transformation. The caterpillar acknowledges its own unattractive state—“I know I’m now among the things / Uncomely to your sight”—but promises future beauty “on splendid wings.” This foreshadowing frames transformation as a gradual, unseen process, reinforced by lines describing how it “went and hid / In some secreted place, / Where none could look on what he did / To change his form and face.” The secrecy of transformation symbolizes inner growth, moral development, and the unseen refinement of character. When the butterfly finally emerges “most beauteous to behold,” covered in “brilliant dye” and “shining wings trimmed with gold,” the poem suggests a revelation of inherent worth previously overlooked. Therefore, Gould uses transformation to challenge superficial judgments and affirm the potential for beauty and goodness in even the humblest beginnings.
3. How does “The Caterpillar” by Hannah Flagg Gould portray human-animal relationships, and what critique does it offer of human attitudes toward nature?
“The Caterpillar” by Hannah Flagg Gould offers a gentle but pointed critique of human disregard for living creatures, exposing the casual cruelty often inflicted on nature. Charles’s initial impulse to crush the worm—“As though it could not feel”—reflects a broader cultural assumption that small or “uncomely” creatures lack value or sentience. The caterpillar’s articulate plea, “Don’t kill me!” disrupts this assumption, granting the creature agency, emotion, and a voice. By allowing the worm to speak, Gould asserts its intrinsic worth and challenges anthropocentric attitudes. The later revelation that the beautiful butterfly was once the despised “worm” illustrates the danger of making value judgments based on appearance. The butterfly’s act of gratitude—“And love and praise you still”—underscores the emotional reciprocity possible between humans and the natural world. Ultimately, the poem critiques human arrogance and urges a compassionate, attentive relationship with nature rooted in empathy rather than dominance.
4. What role does memory and recognition play in the moral message of “The Caterpillar” by Hannah Flagg Gould?
“The Caterpillar” by Hannah Flagg Gould uses memory and recognition to highlight the lasting impact of compassionate choices, even when their consequences may initially go unnoticed. Charles quickly forgets the incident—“when Charles had quite / Forgotten what I’ve told”—demonstrating how small moral decisions often fade from the human mind. In contrast, the butterfly remembers the mercy extended to him, proclaiming, “For sparing me, I long have praised.” The asymmetry of memory underscores the imbalance between those with power and those subject to it: the powerful may forget their actions, but the vulnerable do not. The butterfly’s gentle reminder—“You may not know me, now / My form and name are new!”—creates a moment of ethical recognition that reinforces the poem’s teaching. Through this dynamic, Gould asserts that acts of kindness generate enduring moral “fruit,” even if the benefactor remains unaware. Memory thus becomes an ethical bridge connecting past actions with future consequences.
