The gall's range is computed from the range of all hosts that the gall occurs on. In some cases we have evidence that the gall does not occur across the full range of the hosts and we will remove these places from the range. For undescribed species we will show the expected range based on hosts plus where the galls have been observed.
Our ID Notes may contain important tips necessary for distinguishing this gall
from similar galls and/or important information about the taxonomic status of
this gall inducer.

On The Cynipidous Galls of Florida
William Ashmead
(1887)
Andricus (Trisolenia n. g.) saltatus n. sp.
The Blue Jack Jumping Gall
Galls. — Oblong-oval, longitudinally ribbed, brown galls, without a distinct cell, occurring two or three together and issuing from the bud axils in early spring; they are but slightly attached and fall to the ground on the slightest jarring of the tree.
This gall was discovered three years ago; it appears the last of March, and when first taken from the tree and for several weeks afterwards, has the power of jumping, due to the contractions and sudden relaxation of the larva within; some of them will jump three-quarters of an inch off the table. Out of nearly two hundred galls gathered the first year of its discovery, but one reached maturity; all the rest died. This specimen was just eleven months and some days in the gall. In 188.5 but three specimens were raised, one a male, and the period of development was the same. This year all my specimens seem to be dead, although I collected at different times and endeavored as far as possible to collect the most matured specimens; evidently the season was too dry for them. Last March I collected two females while ovipositing in the buds; the ovipositor was so deeply immersed in the bud as to enable me to capture the flies in my fingers before they had time to withdraw and escape; they agreed perfectly with the bred specimens.
