This is the 3rd year they have been roosting at this location. We have seen them for four days now. Sorry, it's hard to get a great photo

Our report of 100 monarchs is a guesstimate, we had counted 30 in one cluster, but often in the evening they were fluttering around a number of trees. It seems there were 3 places that they mostly ended up in when I checked again early morning, but also there were some smaller groups of 2, 3, 4 monarchs on their own branches a small distance away from the larger groups.

The first time we noticed them roosting this year was Tuesday Sept 3rd, but we had been away for the 2 days prior, so I can't say for sure the first date they were at our place.

As for nectar sources, we have a patch of milkweed growing in our horse pasture, and also have a flowerbed with black-eyed Susan, snap dragon, alyssum growing in close to where they are roosting, a few glads and four o'clock flowers.

Tonight's temperature is to be a low of 8 degree celcius, i cannot say for sure what last night's temperature was, but feel it would have been very similar, except Sept 3rd night was very windy. The wind was coming from the west, and the butterflies would have been somewhat sheltered but not completely.
