Sphingidae -- Sphinx Moth Family
If you grow tomatoes in your yard in the Sonoran Desert or almost anywhere else in North America this large moth will soon find them and lay eggs. The horn worms start out small and will go unnoticed as their green camouflage works quite well at concealment. Suddenly the grower will notice many. many stems with nary a leaf left. It is only then that the huge caterpillars appear and are identified as the ravenous culprit.
