What are these bugs called?

[nrohrbach]

I was given these bugs as a gift and can't seem to find out what they are. Can someone please tell me what the names of these bugs are? Thanks for any help!

Here's the other bug I was given.

Where are they from? A locality of origin is always useful in helping to identify specimens correctly.

The second specimen looks like a Guitar beetle, Mormolyce phyllodes, but I'm not certain as my speciality is one family of butterflies. The first one is some sort of water bug (Hemiptera), but I don't know much about them. Someone else can probably give a better identification, particularly if you tell us where they come from.

First pic : it's probably a Belostomatidae; see the page :

en.wikipedia.org/wiki/Belostomatidae

About the second pic, here is: Mormolyce castelnaudi DEYROLLE, 1862, from Sabah (Borneo, Malaysia), Sukau locality near the Kinabatangan river :



I can't tell more, I'm not hemipterist or coleopterist ! And, as written by Adam Cotton, it's always difficult to identify an insect without the geographical origin.

Thank you for your help everyone! I didn't know the origin for these bug as they were a gift and I'm pretty sure my friend just ordered them from a website. It's nice knowing what these little critters are though so thanks very much!

The first one is almost sure Nepa rubra, certainly Nepidae and not Belostomatidae. For the second, I don't know why jmg told Mormolyce castelnaudi instead the typical Mormolyce phylloides that wisely purposed Adam, all Mormolyce are very similar but any that is not M. phylloides is a rarity in commerce while M. phylloides is commonly seen.
