View 9/12/2024 ARROYO GRANDE CA Monarchs One 2nd instar that was observed on A. fascicularis was dead on the plant. But when I went back for my weekly monitoring later in the week it was not present so it is not in my data. Also on 10/6 not during a weekly monitoring session, I observed a clearly diseased chrysalis growing on a tomato cage. It was dark brown and mushy looking. I posted photo on iNaturalist. I did not really do a survey on these days, I just observed in between surveysDid not want to record in the data columns above because both sightings were deceased
