#ant #蚂蚁 #行军蚁
全异盲切叶蚁（Carebara diversa） 是一种具有明显工兵分化的蚂蚁。在野外，它们的蚁群数量可以达到数十万只，它们的习性也与“行军蚁”颇有相似的地方，有时候也会浩浩荡荡地“行军”
工蚁
体长2.3mm-3.5mm，后头缘不凹陷，上颚齿尖；触角柄节略超过后头缘；复眼位于头部中侧。缺小盾片；并胸腹节刺长而尖，向后发散，略下弯。体光亮，中胸侧板、并胸腹节具细密刻点。体栗褐色至深栗褐色，在整个蚁群中，工蚁的数量会远远大于兵蚁的数量。工蚁通常会聚集在兵蚁或蚁后的身上以此来保护它们
兵蚁
体长4.2mm-23mm，最大型兵蚁深粟褐色；立毛金黄色，较长且稀疏；头前半部及头两侧和并腹胸两侧具纵长细刻纹，头顶、前胸背板前半部和并胸腹节具横细刻纹，腹柄刻纹不规则且有细密的刻点，上颚大部、唇基、头顶中央和后腹部光亮；头矩形，前后等宽，头后缘中央宽凹，中央具一纵沟至额区，1个单眼位于两复眼的正中间，唇基前缘中央略有凹陷，触角脊短且发散；前、中胸背板圆凸，其缝仅稍具刻痕，中胸横脊大且显著突出，并胸腹节刺粗壮且上翘，指向斜上方；腹柄的第一结节侧面观呈三角形，上缘中央具深凹，第二结节圆形，其宽度为第一结节的2倍，小型兵蚁头小得多，无中单眼，头后缘中央仅稍具凹缘，中胸小盾片不甚突出，第一结节上缘凹陷不明显；头和并腹胸的刻纹也更细弱，头顶和前胸背板横细刻纹消失。在上述两型兵蚁之间，存在着多种过渡类型。
兵蚁在整个群落中起着保卫蚁巢和贮存粮食的作用
蚁后
体长约为18-22mm，体色近亮黑色；触角和足深粟褐色。头部单眼大而突出；整个头部几布满纵长细刻纹。其间有刻点存在，但较光亮；上颚刻点粗密。并腹胸光亮，短粗；并胸腹节背板短，具横条纹，其刺短粗且指向后方。后腹部较最大型兵蚁粗长。翅深黄褐色。半透明，翅脉褐色。
雄蚁
体长约为13.0mm，体深褐色；触角和足浅红褐色；上颚、唇基和头前扁平部分为粟褐色。头上部具纵长细刻纹；并腹胸背板刻点细密，但并胸腹节背板基部具纵长刻纹，端部为横条纹；后腹部光滑，具不规则散生的带毛小瘤。
Carebara diversa is an ant with obvious engineer differentiation. In the wild, the number of their ant colonies can reach hundreds of thousands, and their habits are quite similar to those of "marching ants". Sometimes they will "March" in a mighty way
worker-priest
The body length is 2.3mm-3.5mm, the posterior head edge is not sunken, and the upper jaw tooth tip; Tentacle handle nodes slightly beyond the posterior cephalic margin; Compound eyes are located in the middle of the head. Lack of scutellum; And thoracoabdominal spines are long and sharp, diverging backward and bending slightly downward. The body is bright, and the side plate of the middle chest and the thoracoabdominal segment have fine points. From chestnut brown to dark chestnut brown, the number of worker ants in the whole ant colony will be far greater than that of soldier ants. Worker ants usually gather on soldiers or queens to protect them
soldier ant
The body length is 4.2mm-23mm, and the largest soldier ant is dark millet brown; The bristles are golden yellow, long and sparse; The front half of the head, both sides of the head and both sides of the abdomen and thorax have longitudinal fine lines, the top of the head, the front half of the chest backplane and the thoracoabdominal segment have transverse fine lines, the abdominal handle has irregular and fine points, and the majority of the upper jaw, the lip base, the center of the head and the posterior abdomen are bright; The head is rectangular, the front and back are equal in width, the center of the posterior edge of the head is wide concave, the center has a longitudinal groove to the frontal area, a monocular is located in the middle of the two compound eyes, the center of the front edge of the labial base is slightly concave, and the antenna ridge is short and divergent; The back plates of the front and middle chest are round and convex, and their seams are only slightly notched. The transverse ridge of the middle chest is large and prominent, and the spines of the chest and abdomen are thick and upturned, pointing diagonally upward; The first nodule of the ventral stalk is triangular in lateral view, with a deep depression in the center of the upper edge, and the second nodule is round, with a width twice that of the first nodule. The head of the small soldier ant is much smaller, without a middle monocular, with only a slightly concave edge in the center of the posterior edge of the head, the midchest scutellum is not very prominent, and the depression of the upper edge of the first nodule is not obvious; The incisions of the head and abdomen chest are also thinner, and the transverse fine incisions of the top of the head and the back plate of the front chest disappear. There are many transition types between the above two types of soldier ants.
Soldier ants play a role in defending ant nests and storing food in the whole community
queen
The body length is about 18-22mm, and the body color is nearly bright black; Tentacles and feet are dark millet brown. The head monocular is large and prominent; The whole head is almost covered with longitudinal fine lines. There are some engraved points, but they are brighter; The upper jaw is roughly carved. The abdomen and chest are bright and short; The dorsal plate of thoracoabdominal segment is short, with transverse stripes, and its spines are short, thick and point to the rear. The hind abdomen is thicker and longer than that of the largest soldier ant. Wings dark yellowish brown. Translucent, with brown veins.
Male ant
The body is about 13.0mm long and dark brown; Antennae and feet light reddish brown; The upper jaw, base of lip and flat part in front of head are millet brown. The upper part of the head has longitudinal fine lines; The thoracolumbar backplane has fine incisions, but the thoracolumbar backplane has longitudinal incisions at the base and transverse stripes at the end; The posterior abdomen is smooth, with irregular scattered hairy nodules.
