Key characters

Liriomyza strigata is very similar to L. bryoniae and L. huidobrensis in adult morphology (Dempewolf 2004; EPPO 2005). Liriomyza strigata is generally lighter than L. huidobrensis with the inner vertical bristle on yellow ground, but darker than L. bryoniae, particularly on the hind margin of the eye. This species can be readily distinguished from L. bryoniae by the characteristic mines associated with the midrib of the leaves.  Larva with posterior spiracles each with 10 to 12 pores. Because this species is so similar to L. huidobrensis and L. bryoniae, very careful examination of the mines is required before authoritative identifications can be made.There are now robust molecular diagnostic tests to distinguish between the major polyphagous Liriomyza spp. including L. strigata (Kox et al. 2005; Masetti et al. 2006).


The larva of L. strigata forms a distinctive leafmine closely following the main vein toward (and occasionally into) the petiole. It is not considered to be an important pest of agricultural and horticultural crops (Spencer 1989). The eastern boundary of the distribution is not clear, but the old records from Asia need to be re-examined.
