It has clear, membranous wings and a distinctive, spear-like ovipositor extending from its rear, which is a key identifying feature. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Hymenoptera - **Family:** Siricidae - **Genus:** Xeris ## Interesting facts - Adult Xeris spectrum can't eat! They live off energy stored from their larval stage. - Female horntails often lay eggs inside trees that have been dead for a very long time! - Some people mistake these harmless insects for wasps because of their similar colors! - Their larvae tunnel so well, they can stay hidden inside wood for up to three years! ## Special abilities - **Wood-Boring Ovipositor:** Xeris spectrum can drill deep into dead wood using its powerful, saw-like ovipositor to lay eggs safely within tree trunks. - **Symbiotic Fungus Carrier:** Xeris spectrum carries a special fungus that it introduces into trees, which helps its larvae break down wood for food. - **Larval Wood Digesters:** Xeris spectrum larvae have powerful jaws that allow them to tunnel through tough wood, feeding and growing inside trees. ## Measurements & details - **Wingspan:** 20-50 mm - **Size:** 10-25 mm - **Lifespan:** 10-20 days - **Leg Count:** 6 ## Diet & Feeding Adults don't eat, but larvae are herbivores, munching on wood inside trees. - **Age differences:** Adults do not feed; larvae tunnel and eat decaying wood, aided by symbiotic fungi. - **Primary Foods:** pine wood, fir wood, symbiotic fungi - **Foraging Method:** Foraging ## Ecological connections - **Eaten by:** [Hairy Woodpecker](https://www.snappit.app/explore/hairy-woodpecker) (*Picoides villosus*) — Woodpeckers extract larvae from wood. - **Depends on:** Ponderosa Pine (*Pinus ponderosa*) — Larvae bore into the dead wood of pine trees. - **Depends on:** [Grand Fir](https://www.snappit.app/explore/grand-fir) (*Abies grandis*) — Larvae also tunnel through dead fir tree trunks. - **Symbiotic with:** Wood-rotting Fungus (*Amylostereum areolatum*) — The sawfly carries this fungus to help larvae digest wood. ## Traits - [Social](https://www.snappit.app/explore/traits/social): Social animals live in organized groups, cooperating for survival benefits such as foraging, defense, and raising offspring. - [Camouflaged](https://www.snappit.app/explore/traits/camouflaged): Camouflaged describes organisms that possess coloring or patterns that allow them to blend into their environment. - [Colorful](https://www.snappit.app/explore/traits/colorful): Colorful describes organisms or objects displaying a wide range of bright and distinct colors. - [Herbivorous](https://www.snappit.app/explore/traits/herbivorous): This trait characterizes organisms whose diet consists entirely or primarily of plant material. - [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms. - [Diurnal](https://www.snappit.app/explore/traits/diurnal): Diurnal animals are primarily active during daylight hours, typically resting or sleeping at night. - [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 Always watch butterflies from a distance and don't try to catch them. ## Frequently Asked Questions ### How to identify Xeris spectrum? Look for six legs, antennae, three body sections and the shape of the wings. Beetles have hardened front wings; flies have just one working pair.
