Its wings often form a bell shape when resting, allowing it to perfectly camouflage against tree bark and lichens, making it hard to spot. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Lepidoptera - **Family:** Tortricidae - **Genus:** Choristoneura ## Interesting facts - Female moths lay hundreds of tiny green eggs on tree needles. - Its caterpillars prefer the tasty new needles of spruce and fir trees! - Scientists track their populations using special light traps. - Sometimes, millions of these moths can fly at once during outbreaks! ## Special abilities - **Master of Disguise:** Spruce Budworm Moths have mottled wing patterns that perfectly mimic tree bark, helping them hide from hungry birds and other predators. - **Wind Rider:** Spruce Budworm Moths can travel hundreds of kilometers on air currents during mass dispersal flights, helping them find new forests. - **Forest Eater:** Its caterpillars can strip millions of conifer needles, causing widespread defoliation that changes entire forest landscapes. ## Measurements & details - **Wingspan:** 20-30 mm - **Size:** 12-15 mm - **Lifespan:** 7-14 days - **Leg Count:** 6 ## Diet & Feeding Caterpillars munch on conifer needles, while adult moths don't eat at all! - **Age differences:** Caterpillars eat conifer needles; adult moths do not feed. - **Primary Foods:** Picea glauca, Abies balsamea, Picea mariana, Larix laricina - **Foraging Method:** Foraging ## Ecological connections - **Eats:** [White Spruce](https://www.snappit.app/explore/white-spruce) (*Picea glauca*) — Larvae defoliate the new needles, stunting tree growth. - **Eats:** [Balsam Fir](https://www.snappit.app/explore/balsam-fir) (*Abies balsamea*) — A highly favored host tree for the caterpillars, causing severe damage. - **Eaten by:** [Black-capped Chickadee](https://www.snappit.app/explore/black-capped-chickadee) (*Parus atricapillus*) — Birds, like chickadees, prey on larvae and pupae. - **Parasitizes:** Spruce Budworm Parasitoid Wasp (*Apanteles fumiferanae*) — This tiny wasp lays its eggs inside the budworm larvae. ## Traits - [Furry](https://www.snappit.app/explore/traits/furry): Furry describes animals possessing a dense covering of soft hair or fur. - [Solitary](https://www.snappit.app/explore/traits/solitary): Solitary animals live alone for most of their lives, only interacting with others for mating or parental care. - [Camouflaged](https://www.snappit.app/explore/traits/camouflaged): Camouflaged describes organisms that possess coloring or patterns that allow them to blend into their environment. - [Herbivorous](https://www.snappit.app/explore/traits/herbivorous): This trait characterizes organisms whose diet consists entirely or primarily of plant material. - [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life. - [Keystone Species](https://www.snappit.app/explore/traits/keystone-species): Describes a species whose presence and role have a disproportionately large effect on its environment. - [Nocturnal](https://www.snappit.app/explore/traits/nocturnal): Nocturnal animals are primarily active during the nighttime hours, typically resting or sleeping during the day. - [Pollinator](https://www.snappit.app/explore/traits/pollinator): Describes organisms that transfer pollen, enabling the fertilization and reproduction of plants. ## Collections - [Insects](https://www.snappit.app/explore/collections/insects) ## Safety **Danger:** 1/5 · Very low These moths are harmless, but it's best to look at them from a distance. ## Frequently Asked Questions ### How to identify Spruce Budworm Moth?
