Heat up, numbers down
Monday's transect was walked in an unusually high September temperature that averaged 24 degees during our walk around. Conditions were ideal but with only 38 butterflies recorded, our count was a few down on last week's. As usual, we saw more Meadow Browns than any other species with Common Blues second in the number rankings. As we frequently witness, numbers vary from week to week and one year to the next. Here are previous Week 24 counts for comparison: for 2016, 69; 2018,14; 2019, 46; 2020, 38 (we didn't do a transect on week 24 of 2017).
