Oxycarenus lavaterae is an insect belonging to the order Hemiptera and family Lygaeidae. It is commonly known as the "linden seed bug" due to its frequent association with linden trees, although it can also be found on other plants.

This species is native to the Mediterranean region, including the Comunidad Valenciana, and can be recognized by its distinctive features. Below are some characteristics and aspects of its behavior:

• Appearance: The adult bugs are small, measuring about 3-4 mm in length. They have a flat and elongated body with a black head, pronotum, and a reddish-brown to black back.
• Habitat: Oxycarenus lavaterae typically inhabits linden trees (genus Tilia), but it can also be found on other deciduous trees and shrubs. During the warmer months, these bugs can be seen in large numbers.
• Behavior: They are gregarious insects, often forming large swarms on tree trunks and branches. The adult bugs feed primarily on seeds of their host plants, such as those of lime trees.
• Lifecycle: The lifecycle of Oxycarenus lavaterae includes several stages: egg, nymph, and adult. They undergo incomplete metamorphosis, with nymphs gradually developing into adult bugs.
• Significance: Though they may appear in large numbers, these insects are generally harmless to their host plants. They are mainly considered a nuisance due to their presence in urban and suburban areas.

In the Comunidad Valenciana, Oxycarenus lavaterae can be observed throughout the year, with peak activity during the spring and summer months. Their presence is an indicator of the rich biodiversity found in this region.
