continue to collect large caterpillars from milkweed plants and move to rearing cages.
Tropical milkweed plantings:
4th & 3rd rows were eaten before they got 12-15" tall. Row 2 (large plants) are nearly defoliated and row 1 (largest/oldest plants) are looking 'thin. Egg laying continues.
Over the last week (daily), a dozen+ butterflies can be seen flying over milkweed & Mexican sunflower plants. Mating pairs are also seen daily. Tagged & released ~30 adults so far. Disease and parasitoids are numerous this year, a guess is 20% (up form 11% in 17).
