Skimmer dragonfly

The genus Orthetrum belongs to the order Odonata and the family Libellulidae. In agronomy, these insects are not classified as plant pests. Instead, they are highly efficient predators (entomophages) that play a vital role in maintaining the balance of agroecosystems by consuming various smaller insects.

The life cycle of the skimmer dragonfly consists of an aquatic nymph stage and an aerial adult stage. Nymphs develop in freshwater environments, where they hunt aquatic invertebrates, while adults are powerful aerial hunters. This dual existence allows them to control populations of insects in both aquatic and terrestrial settings throughout their development.

There is no evidence of damage to crops by Orthetrum species. Their mouthparts are specifically adapted for capturing and consuming other insects mid-flight or at rest. They do not feed on plant tissues, sap, or roots, nor do they oviposit in plant stems in a way that would cause physiological harm to agricultural crops.

In terms of agricultural value, these dragonflies are considered beneficial agents. By reducing the population density of potential nuisance insects and crop pests, they perform natural biological control. Their presence is a biological indicator of high environmental quality and minimal toxic chemical impact on the farm.

• Promote biodiversity near fields.
• Maintain local water sources for nymph development.
• Avoid broad-spectrum insecticide applications.
• Foster natural pest suppression environments.

There are no control measures required for these insects as they are not pests. Farmers should protect them as allies in integrated pest management strategies. Protecting their natural habitats ensures that these beneficial predators remain present to assist in the long-term sustainability of the agricultural landscape.
