what are these 2 bugs (pics)
« on: March 08, 2012, 10:42:11 PM »
i found these 2 bugs on my lychee leaves.
the first one, i see every year on my lychee leaves when I bring them indoors. i think they start off light green so they are barely distinguishable from the vein of the leaf, and then turn brown as they get bigger. they are always attached to the vein, on the underside of the leaf.
the second one, not sure if i have seen them before

bug 1


bug 2

Definitely scale

And a type of beetle, that's harmless.(I'm guessing)

We don't have it here, but guessing it is either Japanese maple scale, or close relative armoured scale:

It is either a type of armored scale or banana shaped scale (Prococcus acutissimus). Here is an illustrated list of some scale insects:
http://bugguide.net/node/view/5940/bgimage?from=120

BTW, here is an interesting tidbit regarding armored scales I came across:
Not all animals, however, are clones. Sometimes two tiny embryos developing inside their mother will fuse together into a single embryo and continue developing. The resulting animal is not a clone, but a chimera: a conglomeration of two different cell lineages into a single organism. Some species of monkeys (marmosets) typically have chimeric blood, from having shared a blood supply with a twin in utero (Haig 1999), and rare cases of accidental chimerism are known from many animal species (Tremblay and Caltagirone 1973; van Dijk et al. 1996). In marine invertebrates, chimeric individuals often arise from the fusion of individuals later in development (Buss 1987). Here I want to draw attention to a remarkable form of chimerism found in armored scale insects. These insects (Figure 1) always develop not from a single fertilized egg but from two genetically different cells. One of these cells develops into a special organ (the bacteriome, which houses symbiotic bacteria) that has a nuclear genome different from that found in the rest of the body.

I've had the same type of scale on lychees I've purchased from Florida.  Find them, squash them, and then cover the plant in a good hort. oil spray.  Should take care of them.
