Some theologians, in their attempts to define the distinct roles of the Father, Son, and Holy Spirit in the Trinity, have referred to Christ as the form or pattern of creation.  If this is correct, perhaps the pattern of parthenogenesis (virgin birth) found in nature represents a foreshadowing of the ultimate parthenogenesis:  the virgin birth of Christ.
From Wikipedia, here are some relevant passages on parthenogenesis:
Parthenogenesis // is a form of 
asexual reproduction in which growth and development of 
embryos occur without 
fertilization. In 
animals, parthenogenesis means development of an embryo from an unfertilized 
egg cell and is a component process of 
apomixis. 
The word 
parthenogenesis comes from the 
Greek παρθένος, 
parthenos, meaning "
virgin" and γένεσις, 
genesis, meaning "birth".
[1] The term is sometimes used inaccurately to describe reproduction modes in 
hermaphroditic species that can reproduce by themselves because they contain reproductive organs of both sexes in a single individual's body.
Parthenogenesis occurs naturally in many plants, some 
invertebrate animal species (including 
nematodes, 
water fleas, some 
scorpions, 
aphids, some 
bees, some 
Phasmida and 
parasitic wasps) and a few 
vertebrates (such as some 
fish,
[2] amphibians, 
reptiles[3][4] and very rarely 
birds[5])
There are no known cases of naturally occurring mammalian 
parthenogenesis in the wild. Parthenogenetic progeny of mammals would 
have two X chromosomes, and would therefore be female.
In 1936, 
Gregory Goodwin Pincus reported successfully inducing parthenogenesis in a 
rabbit.
[74] In April 2004, scientists at 
Tokyo University of Agriculture used parthenogenesis successfully to create 
a fatherless mouse.
On June 26, 2007, 
International Stem Cell Corporation (ISCC), a California-based stem cell research company, announced that their lead scientist, Dr. 
Elena Revazova,
 and her research team were the first to intentionally create human stem
 cells from unfertilized human eggs using parthenogenesis.
On August 2, 2007, after much independent investigation, it was revealed that discredited South Korean scientist 
Hwang Woo-Suk unknowingly produced the first human embryos resulting from parthenogenesis...This made Hwang the first, unknowingly, to successfully perform the 
process of parthenogenesis to create a human embryon and, ultimately, a 
human parthenogenetic stem cell line.
While admittedly speculative, perhaps the pattern of parthenogenesis in the natural world prefigured the 
most unique virgin birth of the most unique person, of the most unique species, to have ever walked the face of the earth.  After all, wasn't it JRR Tolkien and CS Lewis who often pointed to the old nature mythologies of 'gods dying and rising' as foreshadowings of Christ, the real God-Man, dying and rising from the dead?
