|A BIT ABOUT BUGS
Ribautiana is a moderately diverse genus of generally pale, yellowish typhlocybines with darker markings around the wing apex, normally including discrete spots on three of the veins. Separation of some species is difficult, and dissection can be required for confirmation.
R. debilis is a species with indistinct forewing markings, although diffuse dark spots are still present on the three vein apices. In females and some males, there are two dark spots at the face/vertex transition, and one at the front of the pronotum in some females, similar to the larger R. ulmi. Unmarked specimens need to be dissected.
A local species on a wide variety of hosts, including brambles, apple, hazel, willow and alder.
