She went to Mauritius in 1870 and became acquainted with Nicolas Pike, U.S. consul, who was engaged in collecting natural history specimens for the Louis Agassiz Museum in Cambridge, Massachusetts. She assisted him in the classification of over 800 species of fish, of which she made many colored sketches. They married in 1875 and moved to America, where she contributed articles and illustrations to ''Scientific American'', ''American Agriculturist'', and '' American Garden''.

Spider Web And Cocoon Making
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a ...
