Stag beetle nests

Stag beetle nests have been found in all sorts of places, all they need is decomposing wood.
Moreover according to my local observations, plus other findings via my Stag beetle “larval incidents” in private gardens survey, the females seem to be very quick at finding places where to nest.
Here are a few examples of their nesting choices.

  • Nest in woodland

    Stag beetle larvae were found feeding in the oak log lying on the ground, on the right hand-side of the path, Epping forest.
    This is a classical example, stag beetles are primarily a woodland species.

  • Nest in the root system of an old shrub

    Stag beetle nest found in the root system of a very old forsythia shrub. This nest was found when the shrub was being cleared away because because it was too old.
    This is an interesting example of a nest in ageing wood.

  • Nest above the ground also in a very old shrub

    Several larvae were found feeding in the trunk of an old buddleia shrub; note the wood mould. This nest was also discovered when the shrub was being cut. The trunk and other branches were left in place and heavily mulched with woodchips.
    This is another example of a nest in an ageing shrub but above the ground, which is rather unusual.

  • Nests in buried logs

    Oak stepping logs in a school playground. These logs have been placed in the playground a few years ago and now they are getting old. Stag beetle larvae were discovered in two of them during maintenance work.

  • Nest under unburied logs

    Larvae were found only on the left log, which is the only one that is actually in contact with the soil, and this is very important.

  • Nest under logs set on a membrane

    Larvae found under a log that had been set over a membrane in a private garden. Note the holes that the larvae made in the membrane. Stag beetle larvae like to be in and out of the soil, sometimes.
    This is a remarkable example of their adaptability.
    However if the membrane had been set over an existing nest the emerging stag beetles would have had trouble getting out. See this example of stag beetles that were trapped under a membrane. Fortunately they were released in time.

  • Nest in a builders yard

    Stag beetle larvae and one adult were found in a walnut log in the area in front of the caravan. The tree had been cut five years ago.

  • Nest by a busy street

    Sevearl stag beetles were seen emerging and fighting in Crouch Street, Colchester, by Theo Tamblyn during the evening of 12 June 2009, 4 males and 3 females. Several days later about 10 emergence holes were still visible in the area indicated by the arrow.
    The lime trees currently present in this little patch of unpaved land were planted in 1972 when the area was redeveloped and, presumably, a big tree was felled. It shows a) how long a nest may last b) it really doesn't matter where it is.

    Stag beetles - all they need is love and wood
    To ensure that one needs to plant trees all the time.
    When did you last plant a tree in your garden, or anywhere else?
