The species account records egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding calendar are not established here.
Reproductive mode reported for this named species.
Mode alone does not establish litter or clutch size, seasonal timing, or captive husbandry requirements.
Philippine distribution
The atlas records Oligodon modestus from these named Philippine areas: Luzon, Mindanao, Panay, Negros, Tablas. These are literature areas rather than a continuous range boundary.
Literature documented · Existing checklist occurrence statement and distribution review
The original evidence level is retained.
A country listing cannot establish an island or a precise locality.
Taxonomic context
Oligodon modestus is retained in the atlas’s dated checklist under Colubridae. The authority is GÜNTHER 1864. Earlier names and the original source notes are preserved below for comparison.

Venom classification not yet added · Effects not yet summarised in this atlas
Observe from a distance. Do not handle, corner or capture a snake to identify it. An incomplete venom account is not evidence that a species is safe to handle.
After a suspected snakebite, keep the person still and arrange urgent medical care. Avoid tight tourniquets, cutting, suction and unproven remedies. Do not wait to identify the snake before seeking help.
The original description is available online (see link below).
Distribution: “The type, collected by H. Cuming, is reported from "Philippine Islands;" the exact locality is no longer known. A specimen is recorded from southern Negros, taken by A. Everett. Both these specimens are males. I failed to find this species in my collecting in central and northern Negros; if it occurs there, it is probably very rare.” (Taylor 1922)
