State agricultural officials said Friday that a second wild Mediterranean fruit fly was discovered in Mission Viejo half a mile away from where the first bug was found a week earlier.
The two new sightings bring to seven the number of medflies found in the general area. In July, five were found in adjacent Lake Forest.
"At this point, any fruit fly we find is a concern," said Oscar Hidalgo, spokesman for the California Department of Food and Agriculture. "We're still fortunate that it's in the quarantine zone."
