Citrus bud mite

Citrus bud mite is very small, elongated and somewhat tapered at the posterior end, and has four legs at the front end near the mouth. Adult females lay about 50 eggs mostly in the bud scales of recent growth. Populations peak in summer, and summer and fall blooms are most likely to suffer damage.
Citrus bud mite is primarily a pest of coastal lemons but in recent years has also been found in interior regions of southern California. The mites feed inside the buds, killing them or causing a rosettelike growth of the subsequent foliage and distortion of flowers and fruit, which may or may not reduce yield, fruit quality, or both.
