Leaf beetle (Chrysomelidae).
There are many species of the family of leaf beetles. They usually have striking
colours. They are almost all herbivores. And therefore often harmful. Some species can jump very well.
Flea beetle
(Asiorestia)
It is a general name
applied to the small, jumping beetles of the leaf beetle family,
Chrysomelidae.
Within this family are subfamilies.
This little beetle belongs to the family Asiorestia. (like
Asiorestia transversa, Asiorestia ferruginea) the differences however are very
small. You must examine this beetle, to be able to find
the correct species.
They love young leaves.
They can jump just like fleas. I see them often in June in the goldenrod
2008:
Next year I've flea beetles again.
Haltica oleracea or Altica oleracea.
It lives on the Evening
Primrose. That's the difference with other blue flee beetles. It's also a
good jumper. It damages the plant. But the plant will survive.
Larva Viburnum Leaf Beetle
A leaf beetle,
family Chrysomelidae. But these beetles don't jump. Viburnum Leaf Beetle (Pyrrhalta viburni)
The Viburnum Leaf Beetle lives on different species of
Viburnum. The Guelder-rose, Water Elder (Viburnum opulus) and the Viburnum
tinus. Here it is on a Viburnum tinus in my garden.
They hibernate as an egg deposited in the branches. They hatch in May. The
greenish-yellow larvae cause much damage, but also the beetles feed on the
leaves. Initial infestations will not kill the plants.
In June, the larvae will pupate in the soil.
Europe, Asia, but now also in North America, Canada (In 1947 for the first
time) and from Canada to the USA .
Size 5 - 7 mm.

Scarlet lily beetle (Lilioceris lilii) Family Chrysomelidae.
This shiny, bright red beetle likes lilies and other members of the family
Liliaceae. But the most damage is caused by the larvae.
The beetle don't taste well for birds. The beetle uses the red colour to
warn enemies. The larvae make a protective shield with their own frass.
They overwinter as adults. For several months the females lay eggs on the
underside of a leave. The larva pupate in the ground.
Length: 8 to11 mm.
German: Lilienhähnchen French: criocère
du lis
Oulema melanopus orOulema duftschmidi Family Chrysomelidae.
Oulema melanopus and Oulema duftschmidi are very similar.
The pronotum and legs are bright red. The head and carapace are dark blue. Here it is on a spindle. Small, but very striking.
It lives on grasses and cereals.
Length: 4 - 5 mm.
April - September.
Willow
Leaf Beetle(Lochmaea caprea) or heather
beetle (Lochmaea suturalis)
Lochmaea caprea L. and suturalis without genital examination mostly not distinguishable. Here it is on the flower of a marsh marigold.
Heather
beetle (Lochmaea suturalis)
Lochmaea suturalis lives in areas of heath. But you can find it on
other plants too. Heather
beetles eat the young leaves of the heather. The larvae eat the roots. For the plant,
they are harmful. I live near the dunes with heather. It is possible, it
is a heather
beetle.
Yellow willow beetle (Lochmaea
caprea)
The willow leaf beetle lives on willow, poplar and birch. We have a birch
in our garden. A yellow willow beetle is also possible.
Length: 4 - 6 mm
April - September
