An inventory of the wasp-moths Ctenuchina and Euchromiina (Erebidae) was done for the Tumilco Mangrove, Tuxpan, Northern Veracruz, Mexico. Moth collecting was carried out between September, 2006 and June, 2007 with 20 field trips and with an effort of collection of 140 hours of night work and 140 hours of day collections, adding up to 280 hours of effective work in the field. Two types of collection techniques were used: butterfly nets and mercury light traps, the latter being placed during new moon time. Thirteen species were found: three of them in Ctenuchina and ten in Euchromiina. The month with greater richness and abundance was October.
