However, if I am a monarch colony speeded-up by a factor of 360, then with each hour or two of daylight I have died and been replaced by a child. Furthermore, during my early life I am a caterpillar, and later a butterfly, and in between I have a total meltdown. (See Figure 2.) During all of these life bifurcations, where is my memory of the way home? Sheldrake proposes a morphic field as the storage medium for this knowledge. We might further propose a mathematical model for this field based on chaos theory, that is, a complex dynamical model for a morphic field that functions as a mental field with memory for a colony. In fact, we have already written about such a model in another context, that of the prehistory and history of the human colony on planet Earth, in the book, Chaos, Gaia, Eros.
Global analysis is a branch of mathematics which emerged during the first half of this century. Its project was to rewrite about half of mathematics as a special case of dynamical systems theory, or chaos theory. In particular, the functions of mathematical physics, such as the fields or states of quantum mechanics, were regarded as infinite-dimensional vectors, and the partial differential equations of mathematical physics P such as the wave equation of d'Alembert, the heat equation of Fourier, the Maxwell equations for the electromagnetic field, and the Schroedinger equation of quantum theory P were considered vectorfields (dynamical systems) on the infinite-dimensional state spaces. This ambitious project resulted in a global unification of mathematics and mathematical physics, without clarifying in any way the real natures of the fields, forces, and mechanics of physical nature.
When the fields and equations of physics are transformed into chaos theory, and then prepared as computer programs for computational studies, the infinite dimensional systems are approximated by finite (but high) dimensional systems of the sort known to the theories of chaos, bifurcations, and complexity as cellular dynamical systems. And this is the approach taken by Peter Broadwell and myself in modeling the morphic field of a fish school or bird flock. In fact, we chose the wave equation as the mathematical foundation for our morphic field models, and thus the models tended to vibrate wildly. We taught our model birds to modulate and demodulate this vibrating field to communicate with each other. And this is the sort of model I am now proposing for a colony of monarch butterflies.
We may think of the ensemble of monarchs has little motors maintaining a state of continuous vibration in their collective field. When one dies and another is born -- these are bifurcations -- the field is only slightly affected. (See Figure 3.) The cognitive map of the colony (including the directions for finding the way home) is maintained in the collective field as a chaotic attractor.

Figure 2. A histomap showing 8 months in the life of an eastern colony of monarch butterflies. Dashed lines indicate the caterpillar phase, and solid lines the butterfly stage, of each generation. Numbers count the generations. When butterfly 5 goes to sleep in Mexico in mid-November, it is the same butterfly, now counted as 0, which awakes in mid-March.
Latitude is indicated on the vertical axis, from 20 degrees North (Mexico City, bottom) to 50 degrees North (Southern Canada, top). Time runs along the horizontal axis to the right, for 8 months, beginning in mid-March.
Details taken from ((Cockrell, 1993), for example, arrival north of 41 deg. in mid-June, average travel speed of 24 km/day, typically 5 generations per season, etc. Also, there is an alternate route below (south of) that shown here, with typically 7 generations of monarchs per season.

Biography of a monarch: 1. Egg: five days 2. Birth 3. Larva (caterpillar), 5 instars of 2-7 days: ca 3 weeks. 4. Making the pupa (chrysalis): 1 day 5. Metamorphosis: ca 1 week 6. Butterfly: 2-6 weeks in summer 7. Reproduction: anytime after the first few days 8. Death: shortly after mating Note the overlap of a few days while the parent fails, and the egg grows.
