Curculionidae      

These weevils (Cyrtotrachelus species) live in bamboos and make tasty snacks
  Macrochirus sp leaf-rolling weevil (fam. Attelabidae) Curculio spec.
probably a palm weevil, subfam. Rhynchophorinae perhaps genus Bagous primitive weevil, fam. Brentidae, tribe Cyphagogini

Cicindelidae
Cicindelidae (tiger beetle) Neocollyris cylindripennis ? "tiger beetle" : Cosmodela aurulenta juxtata- there were hundreds of them along a stream saw this one at an elephant camp-  Neocollyris fuscitarsis-no, Therates sp. Wrong again- Heptodonta pulchella Hope, 1831  (Cicindelini: Prothymina: Heptodonta) another resident of our garden-   Calochroa flavomaculata
       
 
another tiger beetle: Cosmodela virgula   all about Tiger beetles   another multicoloured tiger beetle  Cosmodela aurulenta juxtata  Calochroa flavomaculata Cosmodela aurulenta juxtata

There's now a book on Tiger beetles of Thailand by Roger Naviaux so I have even fewer excuses for not identifying things                        

Chrysomelidae
subfamily Galerucinae Lilioceris quadripustulata Lilioceris sp. (maybe impressa or laosensis) Cryptocephalus sp

Podontia, subfamily Alticinae

Podontia, subfamily Alticinae probably Cassida circumdata Aspidomorpha milearis (Cassidinae)
I often find these Sagra beetles (Sagra femorata) in forest clearings doing their early morning tai chi
They also engage in other forms of exercise hispid beetle  family: Chrysomelidae   sub-family: Hispinae

Sagra formosa

Looks like Sagra buqueti but this is only found in Malaysia Sagra sp. Sagra sp.
Coccinellidae

Synonycha grandis (Thundberg 1781)

Lemnia biplagiata (Schwartz, 1808) Ladybirds come with a variety of colours and patterns
Synonycha grandis again Harmonia octomaculata (Fabricius, 1781)   ladybird plus gentlemanbird
plain coloured models are also available ...

HELP! there's a ladybird after me! (Tenebrionidae family)  
     
     

Meloidae

These beetles, which some Thais call 'tiger beetles' can strip a flower in less time than it takes to say 'Coleoptera'  Mylabria cichorii  (Meloidae)

ground beetle of the Carabidae  genus Panageus carrion beetle (fam. Silphidae) Diamesus osculans
