Identifying Flower Midge Infestation

Flower midges, also known as gall midges, are small, delicate flies that belong to the family Cecidomyiidae. These insects are typically less than 3 mm in length and often go unnoticed until they cause visible damage to plants. Identifying a flower midge infestation is crucial in order to take appropriate measures to control and prevent further damage. Here are some key characteristics to look out for when diagnosing a flower midge infestation:

Damage Symptoms

• Stunted growth: One of the most common signs of flower midge infestation is stunted or distorted growth in affected plants. The larvae of flower midges feed on the developing tissues of the flowers or buds, causing them to become deformed and fail to fully develop.
• Galls or swelling: Flower midges lay their eggs in the plant tissue, which results in the formation of small round galls or swelling in the affected areas. These galls may vary in color, depending on the plant species.
• Discoloration: Infested flowers or buds may exhibit discoloration, appearing pale, brown, or black. This discoloration is often a result of the feeding activity of the larvae, which disrupts the normal growth and pigmentation of the affected tissue.
• Wilting: In severe infestations, plants may start to wilt and show signs of overall decline. This is usually a result of the extensive damage caused by the feeding activity of the flower midge larvae.

Visual Identification

When trying to identify a flower midge infestation, it can be helpful to conduct a careful visual inspection of affected plants and plant parts. Look for the presence of small, delicate flies around the foliage, flowers, or buds. Adult flower midges are typically gray or black in color and have long, slender bodies and relatively long antennae. However, identifying the adult insect alone may not be sufficient evidence of an infestation, as the damage caused by the larvae is usually more noticeable.

Larval Identification

To confirm the presence of flower midge larvae, you can carefully dissect an affected flower or bud. Use a magnifying glass to observe the larvae, which are typically small, legless, and white or yellow in color. Pay attention to their size, shape, and distinct body segments, as these characteristics can help differentiate flower midge larvae from other insect larvae that may also infest flowers or buds.

Remember that proper identification of the pest is important to ensure effective control measures. If you are unsure about the presence of flower midges or need assistance in identification, it is recommended to consult with a local horticulture expert or extension service.
