Ichneumon Wasp

What I think is a male Ichneumon sarcitorius (Hymenoptera: Ichneumonidae). In the females the abdomen is red, black and white instead of just black and white.

Tachinid Fly

Prosena siberita (Diptera: Tachinidae), a Tachinid fly with a long proboscis.

Its larvae parasitize scarab beetles.
