Common Name : Rove Beetle


Scientific Name : Class : Insecta


Order : Coleoptera


Family : Staphylinidae

Number of Species : Estimated 47,000




Morphology

The Rove Beetle is less than 1 cm long. The body is dark orange and the tip of the abdomen, the upper abdomen and the head are black. The upper middle iridescent greenish region of the abdomen are the hard wings (elytra). A pair of transparent wings are neatly folded and hidden under the hard wings. During daytime, the beetle will be seen crawling around swiftly with hidden wings resembling ants. When disturbed it raises the abdomen in a threatening gesture like a scorpion and can fly away. It can also run on water swiftly !

Habitat and Feeding Habits

The beetle has been observed in the paddy fields (since 1919), school fields - within the grass etc. It is carnivorous and eats smaller insects. Thus it plays an important role as a biological control of ‘paddy pests’. During heavy rains/ floods, the beetle may migrate to drier areas.



Effects on Humans

The haemolymph in the beetle’s entire body (except the wings) contains the most poisonous animal contact toxin in the world called ‘pederin’ (C24 H43 O9 N) named in 1953. It is 12 times more poisonous than cobra venom ! Dried and stored rove beetle for 8 years still retained it’s toxicity ! Contact collision with the beetle while travelling or sleeping, crushing it on the body or smearing with soiled fingers can cause conjunctivitis and severe dermatitis known as dermatitis linearis, paederus (rove beetle /staphylinidae) dermatitis, whiplash dermatitis etc. In September 2002 an epidemic of dermatitis linearis caused by rove beetles affected thousands of high rise flat dwellers and dormitory students in Penang, Malaysia.





Advice to Affected Residents

Since the beetle is attracted to lights at night, switch off or minimise the lighting and close doors/ windows during the beetle epidemic. Use fine mosquito netting, aerosol insect spray, glue traps etc. Do not sit near lights, do not smash the beetle on the body, just blow it away ! If there is contact with the beetle, immediately wash the affected area with soap and water. Those who suffer severe skin reactions should seek medical attention.



Municipal Control

The Seberang Perai Municipal Council had controlled the beetle epidemic in flats and dormitories with insecticide spraying (ULV and direct spraying) using Pesguard FG 161, glue traps (fly traps), wet and dry vacuum cleaners filled with insecticide inside, UVL electric insect traps, canister blow torch etc. If the insect population is beyond your control, contact MPSP: Tel.

tapi bukan aku ...

Jangan lagi kau sesali keputusanku,
Ku tak ingin kau semakin kan terluka,
Tak ingin ku paksakan cinta ini,
Meski tiada sanggup untuk kau terima

Aku memang manusia paling berdosa,
Khianati rasa demi keinginan semu,
Lebih baik jangan mencinta biar ku dan semua hatiku,
Karena tak kan pernah kau temui cinta sejati

Berakhirlah sudah semua kisah ini dan jangan kau tangisi lagi,
Sekalipun aku tak kan pernah mencoba kembali padamu,
Sejuta kata maaf terasa kan percuma,
S'bab rasa ku t'lah mati untuk menyadarinya

Tapi bukan aku,
S'moga saja kan kau dapati,
Hati yang tulus mencintaimu,
Tapi bukan aku

Berakhirlah sudah semua kisah ini dan jangan kau tangisi lagi,
Sekalipun aku tak kan pernah mencoba kembali padamu,
Sejuta kata maaf terasa kan percuma,
S'bab rasa ku t'lah mati untuk menyadarinya
