Parasitic behavior of Amobia distorta (Diptera: Miltogramminae) and defensive behavior of its hosts, Anterhynchium spp. (Hymenoptera: Vespidae: Eumeninae)

open access: yesEntomological Science, Volume 29, Issue 2, June 2026.
The parasitic behaviour of Amobia distorta and the defensive behaviour of its hosts, Anterhynchium flavomarginatum (native species) and A. gibbifrons (probably non‐native), were observed. Abstract Two Anterhynchium species, A. flavomarginatum and A. gibbifrons, are solitary tube‐renting eumenine wasps that occur sympatrically in Japan.
