# Convoluted Gall Wasp (*Andricus confertus*) The Convoluted Gall Wasp is a tiny insect that makes special round galls on oak trees. These galls are like little homes for the wasp's babies, and they help protect them as they grow. - **Category:** [Insects](https://www.snappit.app/explore/categories/insect) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Habitat:** Forests ![Convoluted Gall Wasp](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Convoluted_Gall_Wasp_%28Andricus_confertus%29_%2810180627194%29.jpg&width=800) Photo: Franco Folini from San Francisco, USA, CC BY-SA 2.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Convoluted_Gall_Wasp_%28Andricus_confertus%29_%2810180627194%29.jpg) ## Appearance The Convoluted Gall Wasp is a tiny, dark-bodied insect, typically brown to black. It has a compact, stocky build with clear wings and short antennae, appearing unassuming compared to the prominent, bumpy galls it creates on oak leaves and twigs. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Hymenoptera - **Family:** Cynipidae - **Genus:** Andricus ## Interesting facts - Gall wasps spend most of their lives hidden inside these plant 'houses' they create. - Some galls feel squishy like sponge, while others are hard as wood! - The lumpy galls it makes are living parts of the oak tree, not part of the wasp itself! - These tiny wasps play a huge role in the forest food web for birds and other insects. ## Special abilities - **Gall Architect:** Convoluted Gall Wasp larvae can chemically command oak trees to grow unique, protective structures called galls, which provide both shelter and food. - **Chemical Commander:** Convoluted Gall Wasp has special chemicals it injects into oak trees that force the plant to create a home and food source just for its babies. - **Generation Shifter:** The Convoluted Gall Wasp can reproduce sexually in one generation and then switch to asexual reproduction in the next, a clever way to increase its numbers. ## Measurements & details - **Wingspan:** 4-8 mm - **Size:** 2-4 mm - **Lifespan:** 10-30 days - **Leg Count:** 6 ## Diet & Feeding Adult Convoluted Gall Wasps may sip nectar, but their larvae feed on the nutritious tissue within oak galls. - **Age differences:** Larvae consume plant tissue inside galls; adults may feed on nectar or honeydew. - **Primary Foods:** Oak leaf tissue, Plant sap, Nectar - **Foraging Method:** Foraging ## Ecological connections - **Depends on:** [California Black Oak](https://www.snappit.app/explore/california-black-oak) (*Quercus kelloggii*) — Provides plant tissue for gall formation and larval development. - **Parasitizes:** California Oak Gall Wasp Parasitoid (*Torymus californicus*) — Its larvae feed on the developing Convoluted Gall Wasp larvae inside the gall. - **Shelter:** Pacific Gall Inquiline Wasp (*Synergus pacificus*) — This inquiline lives within galls created by the Convoluted Gall Wasp. ## 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. - [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 these wasps from a distance, so you don't disturb them or their galls. ## Frequently Asked Questions ### How to identify Convoluted Gall Wasp?
