This wasp, black in colour is also a member of thread waisted wasps (having a thin petiole). This petiole connects mesosomal region to metasomal region of the insect.
The abdomen of Sphex has overlapping tergites and sternites. These have two pairs of wings (whose ends have dotted appearance), larger forewings and smaller hindwings.
Their head and mesosoma are covered generously with white shiny hair.
The female Sphex, will use its sting to inject venom into its prey (for example a cricket), drag the paralysed prey into its next and keep it there for the larvae to feed (a reproductive behaviour similar to Ampulex).
