On 15 August 2012 I received first and second instars from John Richards.
They had been feeding on privet and were moved to Lilac successfully.
They were located and oviposited on 1 August 2013 Box Canyon, Pima County,
Arizona. Larvae emerged 11 August 2013.
First instars were 4 mm. long
Second instar 16 August, 2013, 11 mm. long on 18 August 2013
Third instar 20 August,
12 mm 21 August, 15 mm on 22 August, 20 mm on 23 August, 24 mm on 24
#1 set to molt on 25 August
Fourth instar (#1) 26 August - 25 mm long on 26 August
Fifth Instar (#1) 31 August -2013
#1 Fifth Instar on 1 September 40 mm, on 2 September 47 mm, on 3 September
50 mm, on 5 September 60 mm, on 6 September 60 mm.
#2 Fifth Instar
on 8 September was 75 mm. long and purged liquid the night of 9th September.
The length of these are quite variable from when they are resting and when
they are stretched out to feed.
#1 Purged liquid and spun the cocoon overnight on 7- 8 September 2013
#2 Purged liquid before 8 A.M. 10 September 2013. It had
started to spin in a place where two stems came together. Since that
would have been awkward to move to a place to overwinter, I removed some
leaves and moved the stem. The caterpillar began to re-spin the cocoon after
investigating the new arrangement in detail. It finally put an anchor
down on a leaf at 11:30 A.M. and had the cocoon formed by 7:25
P.M. the same day. I believe it was still silking inside the cocoon
for a time after that. On 4 October 2013, after they had
all pupated inside the cocoons, they were placed in the crisper of the fridge
5 days as first instar
4 days as second instar
6 days as third instar
5 days as fourth instar
9 days as fifth instar
This pupa was taken out of the refrigerator April 7, 2014 and
emerged 27 May 2014 - (Fifty days)
