Bristly Ladybird Rhyzobius lophanthae
Other names: Red-headed Ladybird Red-headed Rhyzobius
This species has spread rapidly in southern England and is associated with Leyland Cypress.
Identification Length 2.0mm
Straightforward if seen well.
Black elytra (wing cases) have distinctive extra long bristles.
The head and pronotum are a brownish red or plum colour, as is the entire underside.
In bright sunshine the head and pronotum can appear bright orange in colour.
On some individuals, and in some dull lighting conditions, the plum colour is darker and at first glance they can resemble one of the all black Scymnus species.

Larvae
The larvae can be found whilst searching for adults and are quite distinctive.
They resemble other typical ladybird larvae but are much smaller.
They are a dark grey with a distinctive pale cream patch in the centre, covering four segments.

Habitat
Has a strong affinity with Leyland Cypress. I have often found them in garden wheelie bins which have been filled with prunings from Leyland Cypress hedges.

I have beaten Bristly Ladybird from an Ivy covered fence but I quickly realised that this was located opposite a large Leyland Cypress hedge.

They sometimes also occur with Arboreal, Red-flanked and Forestier's Ladybirds in garden wheelie bins containing mixed prunings of evergreen shrubs, although they are rarely common.
I have also beaten Bristly Ladybird from Euonymus shrubs, ornamental Juniper and Yew. They are likely to occur occasionally in other evergreen garden shrubs, although are not as frequent in this habitat as the closely related Forestier's or Epaulet Ladybirds.

During 2022 I found this species becoming increasingly common and spreading into other less typical habitats.
I swept one from rough grassland at Canvey Wick, South Essex.
I also started finding them in Ivy alongside Epaulet Ladybirds.
