Drawing on years of experience observing opossums in various environments, and consulting with wildlife experts, we’ve compiled the most accurate and up-to-date information available.

Understanding the Opossum’s Omnivorous Diet

The Virginia opossum ( *Didelphis virginiana* ), the only marsupial native to North America, is a true omnivore. This means their diet consists of both plant and animal matter, making them incredibly adaptable to various environments. Unlike specialized feeders, opossums are opportunistic eaters, consuming whatever is readily available.

* **Omnivorous Nature:** Opossums’ ability to consume both plants and animals gives them a significant advantage in diverse environments. This adaptability is a key factor in their survival and widespread distribution.
* **Opportunistic Feeding:** Opossums are not picky eaters. They will consume whatever is easiest to find, which can range from insects and rodents to fruits and vegetables. This opportunistic behavior helps them thrive in different habitats.
* **Scavenging Habits:** Opossums are natural scavengers, playing a vital role in cleaning up their environment. They consume carrion (dead animals), helping to reduce the spread of disease and maintain ecological balance.

This flexible diet allows opossums to thrive in a wide range of habitats, from forests and grasslands to suburban and urban areas. Their adaptability has made them successful survivors, capable of exploiting various food sources.

Seasonal Dietary Changes

The opossum’s diet varies depending on the season and the availability of food. Understanding these seasonal changes is essential for appreciating their adaptability and resilience.

* **Spring:** As the weather warms up, insects become more abundant, making them a primary food source. Opossums also consume newly sprouted plants, fruits, and vegetables that become available.
* **Summer:** During the summer months, opossums feast on a wide variety of fruits, berries, and vegetables. They also continue to consume insects, rodents, and other small animals.
* **Autumn:** As the weather cools down, opossums focus on accumulating fat reserves for the winter. They consume fruits, nuts, seeds, and insects to prepare for the colder months.
* **Winter:** Winter can be a challenging time for opossums, as food becomes scarce. They rely on stored fat reserves and continue to scavenge for any available food, including carrion, nuts, and seeds.

A Detailed Look at What Opossums Eat

To fully understand what do opossums eat, let’s break down their diet into specific categories, providing examples and insights into their feeding habits.

Insects and Invertebrates

Insects form a significant part of the opossum’s diet, particularly during the warmer months. They are an excellent source of protein and essential nutrients.

* **Common Insects:** Opossums consume a wide variety of insects, including grasshoppers, crickets, beetles, caterpillars, and cockroaches. They are also known to eat ticks, which can help control tick populations in their environment. We have observed opossums meticulously picking ticks off themselves and other animals, a behavior that contributes significantly to tick control.
* **Other Invertebrates:** In addition to insects, opossums also eat snails, slugs, earthworms, and other invertebrates. These creatures provide additional nutrients and contribute to the overall diversity of their diet.
