Ichneumonidae are incredibly diverse, yet there have been few Guatemalan ichneumonid studies. We studied the phenology of 215 specimens of Zagryphus zulaya Gauld (Hymenoptera: Ichneumonidae: Tryphoninae), most captured in a light trap and two Malaise traps in a montane (1850m) forest from 2002 to 2014. One of the Malaise traps caught over 95% of the specimens. The results suggest that Z. zulaya is most abundant in May, June, July, and August, the rainy season. Zagryphus vegai Gauld is newly recorded from Guatemala; it was previously known only from Costa Rica. It was found at an altitude of 1850m, though its previous known range was 700m to 1500m.
