Building an egg case by Javier Aznar González de Rueda by Spain ©
While out on a night walk in the Amazon rainforest near Tena, Ecuador, Javier spotted this little female thorned heart orb weaver spider delicately constructing her egg case. Hanging from a strong silk thread, these female spiders spend hours encasing their eggs in a silken cocoon, which may contain up to several hundred eggs. On this dark night, the egg case resembled a pearly white full moon.
