Rearing the butterfly species Graphium sarpedon I found that almost all caterpillars are infested by parasites.
It turned out to be flies and though I kept 2 specimens I was not able to identify it.
The picture shows a Graphium sarpedon chrysalis with a black dot in it. That is the head of one of the parasites.
This picture is part of the Graphium sarpedon series I put in the observation-column.
It is a 5th instar caterpillar shortly before turning into a chrysalis.
The caterpillar was feeding on the leaves of Neolitsea sericea, "shirodama" in Japanese.

Very small butterfly - probably 1/2 inch long with wings spread, and less tall than long. Moving its wings very rapidly near the ground, before alighting onto this piece of ground cover. This is by the open air ponds belonging to the local wastewater treatment facility, bordering on a bay slough.
