# Jumping Gall Wasp (*Neuroterus saltatorius*) The Jumping Gall Wasp is a tiny insect that makes little galls on oak trees. These galls are like cozy homes for the wasp's babies, and they can jump when they are disturbed! - **Category:** [Insects](https://www.snappit.app/explore/categories/insect) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 2 - **Habitat:** Forests ![Jumping Gall Wasp](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/California_Jumping_Gall_Wasp_%28Neuroterus_saltatorius%29_%2810391639073%29.jpg&width=800) Photo: Franco Folini from San Francisco, USA, CC BY-SA 2.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:California_Jumping_Gall_Wasp_%28Neuroterus_saltatorius%29_%2810391639073%29.jpg) ## Appearance The Jumping Gall Wasp is a tiny insect, typically dark brown to black, with a compact, ant-like body. Some generations are wingless, while others possess clear, delicate wings. It's often distinguished by its surprisingly powerful hind legs. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Hymenoptera - **Family:** Cynipidae - **Genus:** Neuroterus ## Interesting facts - Despite their name, some generations of this wasp cannot fly at all! - Each tiny gall contains a single baby wasp growing safely inside. - They cause oak trees to grow tiny, seed-like galls on their leaves! - They spend most of their life hidden away, tucked inside a leaf gall! ## Special abilities - **Leaping Escape:** Jumping Gall Wasps can jump surprising distances to evade predators, using their strong, spring-loaded legs. - **Tree Architect:** This wasp induces oak trees to grow unique, seed-like galls that protect and nourish its developing larvae. - **Shape Shifter:** Jumping Gall Wasps have two distinct forms in their life cycle: one wingless and jumping, the other winged. ## Measurements & details - **Wingspan:** 2-4 mm - **Size:** 1-2 mm - **Lifespan:** 5-10 days - **Leg Count:** 6 ## Diet & Feeding Adults don't eat much, while their young munch on nutrients from oak trees! - **Age differences:** Larvae consume gall tissue; adults typically do not feed or feed very little. - **Primary Foods:** Oak gall tissue, Oak tree nutrients - **Foraging Method:** Null ## Ecological connections - **Depends on:** [Valley Oak](https://www.snappit.app/explore/valley-oak) (*Quercus lobata*) — Induces galls on leaves for larval development. - **Parasitizes:** Oak Gall Parasitoid Wasp (*Torymus californicus*) — Larvae feed on the developing gall wasp larva inside the gall. - **Eaten by:** [Mountain Chickadee](https://www.snappit.app/explore/mountain-chickadee) (*Poecile gambeli*) — Birds peck open galls to eat the wasp larvae inside. ## Traits - [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. - [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. - [Diurnal](https://www.snappit.app/explore/traits/diurnal): Diurnal animals are primarily active during daylight hours, typically resting or sleeping at night. - [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. - [Miniature](https://www.snappit.app/explore/traits/miniature): Pertaining to species that are significantly smaller than typical or average for their kind. - [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 It's best to look at insects from a distance and not touch them. ## Frequently Asked Questions ### How to identify Jumping Gall Wasp?
