Donisthorpe, 1915, p. 109: “Yellow, narrow anteriorly, 
broad posteriorly; the segments gradually increasing in 
width until quite close to the base. The whole body covered 
with hairs, which are much more abundant in the young 
larvae. The first to the sixth abdominal segments are 
furnished on the dorsum with a pair of long anchor-tipped 
hairs, which are generally absent in the full-grown larvae. 
Some of the other long hairs possess a single hook instead 
of an anchor-tip, some hairs are serrate, and some bifurcate 
or trifurcate.” (Repeated 1927a, p. 117.) Fig. 44 on p. 32

Janet, 1904, pp. 31-32 : “Quant aux petites larves, elles 
s’accrochent les unes aux autres par des poils speciaux. 
Chez la Myrmica, et chez bon nombre d’autres Myrmicidae, 
cet accrochage se fait par de longs poils termines par des 
crochets simples ou double. Ces poils sont disposes regu- 
lierement en petit nombre sur chaque anneau. Les nouveaux 
poils, formes a la suite d’une mue, ne sont pas exactement 
semblable a ceux de la cuticule exuviee.” 
Starcke, 1948, pp. 26 and 28: “The ordinary hookform 
with the head bent perpendicularly to the body or even a 
little further, the thoracal segments ranged fan-like, the 
abdomen next without any special demarcation, straight, 
and only the extremity a little swollen, with some whitish 
spots of urate cells shining through. Usually the head is 
for one third sunk into the prothorax. With the fullgrown 
larva, the head grows still more into the prothoracical seg- 
ment, until more than half its volume is situated there . . . 
There are 13 postcephalic segments of which the last 3 or 
4 are not clearly marked. Newly emerged larvae are portly 
and hooklike from the start . . . The head, of a 3 mm larva 
is 0.42 mm long and at the rear end 0.36 mm broad, the 
mouth parts are 0.24 mm broad. The most protruding part 
is the distal sensilla-turret of the maxilla, but the labrum 
and mandibula do not stay back very far.”
