Yes fall migrant monarchs occur in Albuquerque, but you'd need to find an abundant nectar source like roadside sunflowers or rabbitbrush to have a reasonable chances of seeing and catching any. In the cropland south of Albuquerque along the Rio Grande River you might see adults nectaring in fields of blooming alfalfa Within the city you're best chance of seeing adults would probably be a residential yard with blooming butterfly bushes. Best time to see migrants would be about Sept. 20 - Oct. 20 and especially Sept. 25- Oct. 10
In late Sept. 1999 a commercial monarch breeding company air mailed 1,200 tagged monarchs from California to Albuquerque for release

Two of these were found at overwintering sites along the south-central California coast and one at an overwintering site in Michoacan, Mexico.
