Why Does My Citrus Tree Have Citrus Leafminer?
Citrus leafminers are small insects that attack young citrus leaves. Although the adult insect is a tiny moth, the damage is caused by the larvae feeding between the surfaces of newly developing leaves.
Many homeowners first notice strange squiggly trails winding through the leaves. These tunnels are a classic sign of citrus leafminer activity.
As the larvae feed, leaves often become distorted, curled, twisted, or misshapen. Young citrus trees are generally more affected than established trees because they produce more tender new growth.
Common signs of citrus leafminer damage include:
- Squiggly lines on leaves
- Curled foliage
- Twisted new growth
- Damaged leaf surfaces
- Silver-colored feeding trails
- Distorted leaves
- Damage concentrated on new growth
While leafminers rarely kill citrus trees, heavy infestations can reduce the quality of new growth and place additional stress on already weakened trees.
Many homeowners mistake leafminer damage for disease. Fortunately, the distinctive winding trails usually make identification easier than many other citrus problems.
Proper diagnosis is important because not all curled or distorted leaves are caused by citrus leafminers.
Can Citrus Leafminers Kill A Citrus Tree?
Healthy mature citrus trees usually tolerate moderate leafminer activity. Young trees are generally more susceptible because they rely heavily on new foliage for growth.
If your citrus tree has squiggly trails, curled leaves, twisted growth, or other unusual symptoms, a professional evaluation can help determine exactly what is happening.
