That would [will] be a fun one. lol
I think I'd start with a couple short pieces of dowel sharpened in a pencil sharpener to two different tip diameters, maybe a 1/16 and 1/8. I'd start by putting the 1/16 bluish colored dots along each side of the mold relative to where they are in the pictures. Then I'd cover those with the 1/8 in black. Since you're not going to be able to replicate all that fuzz that lies along the sides for the length of the bugs I'd try to imitate the color for one plastic and then do a darker color to do the top. You have two different color shots. In the one I think that the 20, green pumpkin brown with a liberal dose of bronze hi lite would get you pretty close while the other worm below is more of a green, maybe the #21 green pumpkin green with either the bronze or maybe copper hi lite or even a combination of one of those colors along with green hi lite. Of course, you'd want a twin injector to laminate. Or hand pour one color and finish with a single color if the mold doesn't cater to the twin injector's use. If you really wanted to get fancy, you could thread a few feather fibers thru a needle and pull them thru the injected worm to get the fuzzy appearance.
