Kelly's flesh fly

Kelly's flesh fly (Blaesoxipha kellyi) is a dipteran insect belonging to the Sarcophagidae family. Unlike many members of this family associated with decaying matter, this specific species is specialized as a parasitoid, primarily targeting members of the order Orthoptera.

The primary hosts for this insect are various species of grasshoppers. By infesting these agricultural pests, Blaesoxipha kellyi serves as a natural enemy that contributes to the suppression of grasshopper outbreaks, effectively protecting cereal crops and rangelands from severe damage.

The life cycle is marked by viviparity. The female fly deposits larvae directly onto the grasshopper's body. These larvae bore into the host, feeding on its internal tissues for development. Once the host dies, the mature larvae exit the carcass and pupate in the soil to emerge as adults.

From an agronomic perspective, this insect is considered highly beneficial rather than a pest. Its presence in the field is an indicator of a healthy, balanced ecosystem capable of providing natural biological regulation of crop-destroying orthopterans.

To preserve the population of this beneficial insect, agricultural producers should focus on:

• Reducing the use of broad-spectrum insecticides that harm beneficial fly populations.
• Implementing Integrated Pest Management (IPM) strategies to target grasshoppers specifically.
• Preserving wildflower strips that provide necessary nectar sources for adult flies.
