In 1999 we were given a few Cecropia caterpillars to raise.
We fed them crab apple leaves until they "spun up".
They over-wintered in the garage and emerged the next June.
We kept the moths in our guest room and they layed their eggs
on the window screen; the window sill; the wall; the floor.
The baby caterpillars hatched and the cycle started again.
This was the last year they were allowed in our guest room,
however.

Spring 2002 -- I modified this old bird cage -- lined it
with window screen -- and kept the moths inside when they
emerged. I kept enough pairs to insure that at least one female
would lay eggs.

A row of eggs layed on an old paint rag hung on the cage door
(above). These eggs are coated with an encredibly sticky glue
-- nearly impossible to remove (reason these moths are no longer
welcome in the guest room). |

After getting one mating pair I open the door allowing the
rest to leave as they emerge. This young couple only made
it as far as the deck where they settled in for a days "work".
The Cecropia are a member of the silk moth family and a relative
of the Gypsy Moth. But unlike their imigrant relatives the Cecropia
are are not voracious eaters and pose no such danger to the
environment. They are also much loved by birds (while caterpillars)
and bats (while moths). They are also affected by the bacteria
that many cities spray to control the Gypsy Moth.

This year I saved 14 caterpillars (I give away the rest).
Instead of bringing leaves inside, this year I put caterpillars
inside net bags that are tied out on the tree branches.
Madison used to spray the bacteria (b-t) to kill the Gypsy
Moth. This is non-selective and kills any moths species in
the silk moth family. In 2001 Madison switched to spraying
a pheromone that 'confuses' the male gypsy moth into mating
anything they happen to see -- and hopefully not female gypsy
moths. Pheromones are highly selective for species and this
new strategy will help save the Cecropia (if more towns do
it).

These are incredible creatures. They have dignity and grace.
They have a self assured confidence They don't hurry anything:
Emerging, mating, laying eggs, eating, spinning, metamorphosing/hibernating,
mating, etc, etc... |
