Snakeflies (order Raphidioptera) are fascinating insects known for their elongated neck-like prothorax, transparent wings, and predatory behavior. Found across Europe, Asia, and parts of the Himalayas, these species play an important role in controlling pest populations like aphids and caterpillars. In this article, we’ll explore 15 different types of snakeflies, highlighting their unique features, habitats, diets, and behaviors that make them both ecologically valuable and scientifically intriguing.
1. Raphidia flavipes
Raphidia flavipes is one of the most widespread snakeflies found in Europe. Known for its long prothorax and distinctive wings, this species is often observed in forested areas where it plays a role as a predator of small insects. Its name “flavipes” refers to the yellowish legs, which help in identification.
Identification
- Long, slender body with an elongated neck-like prothorax
- Transparent wings with fine venation, held roof-like over the body
- Legs typically yellowish, a key trait of this species
- Females possess a long ovipositor for laying eggs in crevices
Habitat
This species prefers woodland areas, particularly deciduous and mixed forests. They are commonly found resting on leaves, bark, or shrubs during warm months.
Diet
Raphidia flavipes is predatory, feeding mainly on aphids, small larvae, and other soft-bodied insects. Both larvae and adults contribute to controlling pest populations.
Behavior
Adults are most active during the warmer months, often flying short distances between trees and shrubs. They are diurnal, spending much of the day hunting prey. Females are frequently observed searching for suitable egg-laying sites in tree bark.
2. Raphidia notata
Raphidia notata is a distinctive species of snakefly found across parts of Europe and Asia. It is well recognized for the small dark spots or markings on its wings, which set it apart from many other members of the Raphidiidae family. This species thrives in wooded areas where prey is abundant.
Identification
- Slender body with elongated prothorax resembling a “neck”
- Clear wings with characteristic dark spots or notations
