Robotic insects, a petting zoo, a dog show and a classic bike display are all promised at the annual exhibition which starts in the Botanical Gardens on Thursday.

The show, a revamped version of the Agricultural show, is Bermuda's biggest community event said Environment Minister Dennis Lister, and could attract up to 20,000 people over the three days.

He said: "We have incorporated a wide variety of exhibits and activities that reflect the diversity of interests pursued by the people of Bermuda."

Primary schools have built models of insects with moving parts.

Mr. Lister said: "This is a fascinating project that blends technology with environmental awareness.

"I am amazed by what our students have created and I want to commend the instructors who have worked hard with the students to develop this exciting new exhibit."

In a departure from tradition, different events will take place in the main arena on each day.

On Thursday there is a dog agility show, on Friday the parishes will compete in a relay race and on Saturday there is a classic bike display.

School choirs, dance groups, bands and gombeys will perform. A puppet show and martial arts display is being staged in the southern end of the botanical gardens.

The professional cake display returns after a five year absence while the Folk Live Festival exhibits, which wowed Washington in 2001, will return in a smaller form and show off some of Bermuda's traditions. It will be stage on the grounds outside Camden.

Although the exhibition has expanded its focus it will still feature home-made foods, woodcraft and educational exhibits as well as agricultural and horticultural displays, livestock and show ring equestrian events.

An expanded petting farm features goats and pigs while children can also learn how to milk a cow.

Parks Director Candy Foggo said: "They are very friendly and used to having children come up to them."

Mr. Lister said students had been learning animal husbandry and had helped collect the livestock which would be shown.

He said: "They have participated in showmanship classes to prepare them to show goats and pigs at the exhibition and on the three days of the exhibition they will be assisting with the animals.

"This programme was most successful last year and has attracted a dedicated group of students again this year, some of whom have expressed an interest in pursuing veterinary science as a career."
