Insects are preyed on by birds and other enemies whose sight is probably sharper than ours, and every grade in resemblance which aided an insect to escape notice or detection, would tend towards its preservation; and the more perfect the resemblance so much the better for the insect. Considering the nature of the differences between the species in the group which includes the above Ceroxylus, there is nothing improbable in this insect having varied in the irregularities on its surface, and in these having become more or less green-coloured; for in every group the characters which differ in the several species are the most apt to vary, while the generic characters, or those common to all the species, are the most constant.<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<p style=\"text-align: justify;\"><em>Tampoco puedo yo encontrar fuerza alguna en la objeci\u00f3n de m\u00edster Mivart referente a \u00ablos \u00faltimos toques de perfecci\u00f3n en el mimetismo\u00bb, como en el caso citado por m\u00edster Wallace de un insecto f\u00e1smido (Creoxy1us laceratus), que se asemeja a \u00abun tronquito cubierto por un musgo reptante o Jungermannia\u00bb. Tan completa era la semejanza, que un ind\u00edgena daiac sosten\u00eda que las excrecencias foli\u00e1ceas eran realmente musgo. Los insectos son presa de p\u00e1jaros y otros enemigos, cuya vista probablemente es m\u00e1s aguda que la nuestra, y todo grado de semejanza que ayude a un insecto a escapar de ser observado o descubierto, tender\u00e1 a conservarse, y cuanto m\u00e1s perfecta sea la semejanza, tanto mejor para el insecto. Considerando la naturaleza de las diferencias entre las especies en el grupo que comprende el Creoxylus citado, no es improbable que en este insecto hayan variado las irregularidades de su superficie, y que \u00e9stas hayan llegado a tomar un color m\u00e1s o menos verde; pues, en cada grupo, los caracteres que difieren en las distintas especies son los m\u00e1s adecuados para variar, mientras que los caracteres gen\u00e9ricos, o sea, los comunes a todas las especies, son los m\u00e1s constantes.<\/em><\/p>\n<p>Lectura aconsejada:<\/p>\n<p><a href=\"https:\/\/digital.csic.es\/handle\/10261\/76630\">\u00a0Manual para detectar la impostura cient\u00edfica: Examen del libro de Darwin por Flourens.<\/a> Digital CSIC, 2013. 225 p\u00e1ginas.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Lo que no es improbable, pero tampoco probable, lo toma el autor por indudable\u2026.. &nbsp; &nbsp; 354 \u00a0 Nor can I see any force in Mr. Mivart&#8217;s difficulty with respect to \u00abthe last touches of perfection in the mimicry;\u00bb as in the case given by Mr. Wallace, of a walking-stick insect (Ceroxylus laceratus), which resembles \u00aba stick grown over by a creeping moss or jungermannia.\u00bb So close was this resemblance, that a native Dyak maintained that the foliaceous excrescences were really moss.
