Fan-winged net-winged beetle

Metriorhynchus rhipidius is a species of beetle belonging to the Lycidae family within the order Coleoptera. These insects are easily recognized by their elongated bodies and vibrant colors, which serve as aposematic signaling to warn predators of their chemical defenses.

While often found in forest environments, these beetles can impact agricultural crops when they migrate to adjacent orchards or plantations. They are primarily known for causing damage to woody plants, where both adults and larvae may interact with plant tissues during their active growth phases.

The biological cycle follows a complete metamorphosis, including egg, larva, pupa, and adult stages. Larvae typically develop under bark or within decaying organic matter. However, their dietary habits can shift toward living tissues under specific environmental stressors, potentially threatening the health of decorative or fruit trees.

The damage caused by these insects involves the consumption of bark or young shoots, which weakens the plant's structural integrity. Such feeding behavior creates entry points for secondary pathogens, such as fungal spores or bacteria, which can lead to rapid decay and poor development of the crop.

Effective management strategies focus on preventing the buildup of beetle populations through sanitation. This includes the following measures:

• Regular removal of dead wood and forest debris near plantations.
• Monitoring of tree health to detect early infestation signs.
• Application of targeted insecticides if the pest threshold is exceeded.
• Maintaining soil moisture to prevent plant stress.
