Monarch, Captive-Reared
Sightings report image

Date: 11/04/2019

Number: 1

Final count for 2019--

Brought in 168 monarch eggs/caterpillars

80 healthy monarchs released
11 euthanized (OE or had weak legs)
56 died from tachinid or other parasite
21 eggs didn't hatch

Notes:

- Most that died of tachinid/parasites were brought in as 1 or 2 instars.

- Found many that died of tachinid on the outdoor plants.

- Also preying mantis, orb spiders, assassin bugs were ample in the garden this year and were feasting on the butterflies and cats.

- Still have cats on my milkweed. Don't expect them to survive due to tachinid and other parasites. Haven't seen any survive outside past 4 instar.

- Expect temperatures to drop by December (hopefully) and the milkweed will go dormant. Having an extremely warm and dry Fall.

-Wildfires have been close, but not as close as last year... Noticed that the butterfly population in general seemed to rebound this year. Hope it continues into 2020!
