Citrus leafminer

Phyllocnistis citrella

Adult citrus leafminers are tiny moths about 2 mm long (less than 0.12 inch) with a wingspan of about 4 mm (or about 0.25 inch). They have silvery and white iridescent forewings with brown and white markings and a distinct black spot on each wing tip. Moths are most active from dusk to early morning and spend the day resting on the undersides of leaves, but are rarely observed. Soon after emerging from the pupal case, the female emits a sex pheromone that attracts males. Females lay eggs singly on the underside of leaves. Newly emerged leaflets (flush), particularly along the midvein, are the preferred oviposition site.
