"H. heurippa" is found on the eastern slopes of the
Andes Mountains inColombia .cite web |url=http://www.tolweb.org/Heliconius_heurippa/72255 |title=Tree of Life Project: "Heliconius heurippa" |accessdate=2008-02-27 |format= |work=]Hybridation
The color pattern of "H. heurippa" appears to be a combination of the patterns found on "H. cydno" and "H. melpomene". Natural hybrids from
San Cristóbal, Táchira ,Venezuela , display wing patterns very similar to "H. heurippa", supporting the hypothesis of a hybrid origin for the species.cite web |url=http://news.bbc.co.uk/2/hi/science/nature/5080298.stm |title=BBC NEWS: Two species become one in the lab | Science/Nature | Two species become one in the lab |accessdate=2008-02-27 |format= |work=]A team from the
Smithsonian Tropical Research Institute inPanama attempted to recreate "H. heurippa" by breeding "H. cydno" with "H. melpomene".cite web |url=http://sciencenow.sciencemag.org/cgi/content/full/2006/614/2 |title=Putting One and One Together |accessdate=2008-02-27 |format= |work=] In only three generations of hybridization, the investigators developed butterflies with wing patterns almost identical to those of "H. heurippa"cite journal |author=Mavárez J, Salazar CA, Bermingham E, Salcedo C, Jiggins CD, Linares M |title=Speciation by hybridization in Heliconius butterflies |journal=Nature |volume=441 |issue=7095 |pages=868–71 |year=2006 |pmid=16778888 |doi=10.1038/nature04738] that may be very similar to the first "H. heurippa" individuals.Butterflies within "Heliconius" are "extremely choosey" about finding mates with wing patterns that match their own,cite web |url=http://www.sciencedaily.com/releases/2006/06/060616135623.htm |title=Butterfly Speciation Event Recreated |accessdate=2008-02-27 |format= |work=] and "H. heurippa"
H. heurippa males given a choice between mating with females of H. heurippa, H. cydno, or H. melpomene species were 75 to 90 percent more likely to choose their own kind, and similarly discriminating when presented with photographs of wing patterns instead of actual mates. The wing patterns of "H. heurippa" individuals also make them undesirable as mates for members of their parents' species as well, demonstrating evidence of
reproductive isolation between "H. heurippa" and its putative parental species.cite web |url=http://www.newscientist.com/channel/life/mg19025564.200-hybrids-when-two-species-become-three.html |title=Hybrids: When two species become three - life - 15 June 2006 - New Scientist |accessdate=2008-02-27 |format= |work=]Skeptics wish to see further
genetic sequencing demonstrating that wild "H. heurippa" is a hybrid similar to the laboratory-developed animals. There is evidence to suggest that thegenome of "H. heurippa" may be a mosaic.The species "
Heliconius timareta " and "Heliconius pachinus "cite journal |author=Kronforst MR, Salazar C, Linares M, Gilbert LE |title=No genomic mosaicism in a putative hybrid butterfly species |journal=Proc.
