Ova
The Females and two one gallon
potted Ponderosa Pines were put in a transparent bin with a chiffon
cover after feeding them with honey water. I left
them in a
room with no windows with some lights on for a day or two with no
success. One female died the second day. I then moved them to the
covered patio on the north side of my home that receives no direct sun
but is brighter than indoors. Temperatures were higher on the
patio
than in the house (91 F on Monday, 88 F on Tuesday, Wednesday 93 F ) A
second female died. But with this arrangement the two remaining
females
oviposited on
the Ponderosa Pine - Pinus ponderosa
. The females were
offered honey water in the morning, middle of the day and in the
evening. They were put in a dark cupboard
each night, not in a refrigerator.
The ova were left on the potted pines and kept outside for the
winter. The potted pines were set in buckets with holes drilled in the
bottom for drainage but with a screen placed around the bottom of
the bucket to keep insects out. Wires were fixed into an arch
over the bucket with a net cover over the top to keep insects out. The
net covers were five gallon paint strainers.
Larvae
First Instars began hatching 2 May 2013. Some were transferred to
other potted Ponderosa
Pines.
4 May 2013 they are still trying to feed on the Ponderosa but many have
dropped off and died. I moved some to a Pinyon Pine to see
if that is more palatable but since they are 2 days old, that
probably isn't an option. At this stage they feed gregariously so
I have placed about 6 per pine needle.
