The redheaded pine sawfly, European pine sawfly or Neodiprion sertifer, is a sawfly species in the genus Neodiprion. Native to Europe, it was accidentally introduced to North America in 1925, where it has established itself as a commercial pest. [1] The larvae of Exhyalanthrax afer feed on N. sertifer cocoons.
A small sawfly larvae is seen resting on the vein of a leaf. Sawfly larvae look like caterpillars, but Lowenstein says it's important to note there is a difference between the two in order to ...
In Europe, the larvae of Acantholyda erythrocephala are attacked by the parasitoid Tachinid fly Myxexoristops hertingi.In 2002, 2003 and 2004, in an effort to initiate a biological control programme in North America, pupae of this fly were imported from Italy and released in Ontario in an area of red pine (Pinus resinosa) infested with sawfly larvae.
The larvae feed on pine needles. [3] [4] Eggs are laid in rows in springtime, on pine needles from the previous year. Young caterpillars start feeding on the old needles near where they hatched, leaving the vascular bundles uneaten. Older caterpillars feed more widely, moving to other branches and eating whole needles except for the leaf sheath ...

[52] Black grouse (Tetrao tetrix) chicks show a strong preference for sawfly larvae. [53] [54] Sawfly larvae formed 43% of the diet of chestnut-backed chickadees (Poecile rufescens). [48]

Larvae are often gregarious, and sometimes there can be major outbreaks, thus these sawflies can be major forest pests at times. [1] These sawflies have the ability to compromise the health and ecological balance of forests. When the temperatures begin to rise, the sawflies become strengthened pests to these conifers.
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection.
