Small immature thips feeding on culantro (Eryngium foetidum) leaves.  Body length of largest is about 0.8 mm.  They feed adjacent to the midriff and cause significant silvering.  Many carried fecal matter on their raised abdomen.  No adults were collected.

My guess is that this is the greenhouse thrips, Heliothrips haemorrhoidalis (Bouché).  This species was reported from Guam by D. Nafus in An Insect Survey of the Federated Satates of Micronesia and Palau, SPC Technical Paper No. 210. 1997.
