We captured and tagged another 137 Monarchs and ran out of tags. On 6 October we tagged 130 Monarchs and using a simple capture/recapture calculation (Lincoln Index); we recaptured only 7 monarchs from the day before, we estimate 2,000 Monarchs for that one field. Rough estimate since many Monarchs left the area after we tagged them. The entire 1,200 acre area probably held several thousand Monarchs. Certainly roosting there (individually, not clusters, under dense patches of vegetation?). Necturing almost solely on Pennsylvania Smartweed.
