NOTES ON A GALL MITE OF THE NETTLE TREE (Celtis occidentalis)
Published online by Cambridge University Press: 31 May 2012
Extract
Gall, formed on the under side of the leaf, pear-shaped, half an inch long, forms a cup-like indentation on the upper surface. I have counted eighteen galls on one leaf. One mite in a gall.
Mite, one-tenth of an inch long. Eyes large and protuberant, light red. Antennæ moniliform, ten-jointed—the basal joint and that next it being much larger than the rest. Proboscis for suction. Four undeveloped wings—mere protuberances in the case of some (probably younger) specimens—generally translucent, but in some instances smoky brown. Legs, six in number, hairy, semi-transparent. Abdomen much enlarged, topshaped, the three last segments reddish brown. Tuft of terminal spines of the same color. The creature has a gelatinous appearance; and this, together with its agitation when disturbed, reminds one of Young Blight's description of Old Dolls: “All a-shaking like glue monge.” It attains its growth in August and becomes quiescent.
