Sawfly Larva
Scientific Name: Tenthredinidae (as larvae are hard to identify to genus/species from image alone)
Order & Family: Order: Hymenoptera, Family: Tenthredinidae (common sawflies) or other sawfly families within Symphyta.
Size: Larvae can range from a few millimeters to several centimeters, typically 1-3 cm depending on the species and developmental stage.
Natural Habitat
Sawfly larvae are typically found on the foliage of their host plants, which can include trees, shrubs, and herbaceous plants in gardens, forests, fields, and urban landscapes.
Diet & Feeding
The larvae are herbivorous, feeding on the leaves of various plants, trees, and shrubs depending on the specific species of sawfly. The yellow and black striped pattern might indicate a host plant preference.
Behavior Patterns
Larvae of sawflies are plant feeders and can often be found on the leaves of their host plants. They are not true caterpillars (which are moth/butterfly larvae) but mimic their appearance. Adult sawflies are typically short-lived and focus on reproduction.
Risks & Benefits
Potential risks include defoliation of host plants, which can be a nuisance in gardens or agriculture if infestations are severe. Generally, they pose no direct risk to humans (they do not sting or bite). Benefits include being a food source for birds and other predators in the ecosystem.
