Dasineura serrulatae
Dasineura serrulatae is a species of gall midge in the family Cecidomyiidae, a group of small flies known for inducing plant galls. The species was described by Osten Sacken in 1862. Like other Dasineura species, it likely forms galls on specific host plants, though detailed host associations and biological data remain limited in the provided sources.
Lasioptera solidaginis
Lasioptera solidaginis is a species of gall midge in the family Cecidomyiidae, first described by Osten Sacken in 1863. It is one of numerous gall-forming insects associated with goldenrod (Solidago) plants. The genus Lasioptera includes species that induce galls on various host plants, with larvae developing within these specialized plant structures.
Phylloxera caryaefallax
pecan leaf phylloxera
Phylloxera caryaefallax, commonly known as the pecan leaf phylloxera, is a small, soft-bodied, gall-forming insect closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), causing distinctive galls to form exclusively on leaf tissue. Unlike the related pecan phylloxera (Phylloxera devastatrix), which attacks shoots and nuts and causes more severe economic damage, this species is generally less destructive though heavy infestations can cause defoliation. The insect has a complex life cycle involving multiple generations per season and overwinters as eggs protected within the bodies of deceased females.
