Ray Spider Egg Sacs

Description:

These two egg sacs look very much like the example shown in https://bugguide.net/node/view/2028350..... The egg sac featured in that article was from a Theridiosoma sp. in the Family Theridiosomatidae. A quick check, with Wikipedia, revealed the presence of the Genus Tagalogonia in the Philippines and even better, there are only two species in that genus - Tagalogonia banahaw and Tagalogonia isarog, both of which were documented by Labarque & Griswold, 2014.

Habitat:

Spotted in the farm on a Mango Tree (Mangifera indica Linn.) locally known as Mangang-kalabau. Plant information from - http://www.stuartxchange.org/Mangga.html...........

Notes:

Both of these egg sacs have little holes cut in the sides. These holes might have been made by emerging spiderlings, but it seems more likely that they are access holes cut by predacious parasites. I will try to keep an eye on them, but even if the spiderlings have already hatched (or have been killed by predation), the egg sacs are the best possible indicators of the presence of at least one of the two Tagalogonia spp. in the farm and possibly still on that particular Mango Tree. Always optimistic :-)
